The SP481, SP483, and SP485 devices from MaxLinear are pin-to-pin compatible with this device. The typical application diagram for the SP3485 is displayed in the image below.SP3485 Diagram SP3485 DriverThe SP3485's driver outputs are differential outputs that adhere to RS-485 and RS-422 standards. Without a load, the usual output voltage swing ranges from 0 to 3.3 volts.  The drivers can sustain voltage levels more than 1.5V with a load of 54 across the differential outputs. An active HIGH driver enable control line is present in the SP3485 driver. The differential driver outputs are turned on by setting DE (pin 3) to logic HIGH. The driver outputs will be tri-stated if the DE (pin 3) is logic LOW.The SP3485 driver can handle speeds of up to 10Mbps. The 250mA ISC maximum limit on the driver output allows the SP3485 to withstand an infinite short circuit over the -7.0V to 12V common mode range without catastrophic damage to the IC. SP3485 ReceiverThe differential inputs of the SP3485 receiver have an input sensitivity of 200 mV. The receiver's input impedance is 12k minimum. The vast -7V to 12V common mode range allows for significant ground potential variances between systems. A fail-safe function included into the receiver ensures that even if the input is left unconnected, the output will always be in the HIGH state. The SP3485's receiver can handle up to 10Mbps of data.An active LOW enable control line is included on the SP3485 receiver. The differential receiver will be activated by a logic LOW on RE (pin 2). The receiver of the SP3485 is turned off by a logic HIGH on RE (pin 2). SP3485 Low Power Shutdown ModeYou can start the low-power shutdown mode by making both RE and DE high. The gadgets normally only need 50nA of supply current during shutdown. The part is guaranteed not to reach shutdown if RE is high and DE is low for less than 50 ns. RE and DE can be driven simultaneously. The parts are assured to undergo shutdown if the inputs remain in this state for at least 600 ns.A low-power shutdown state is not assumed for enable times tPRZH, tPZH, tPRZL, and tPZL. Allowable timings tPRSH, tPSH, tPRSL, and tPSL imply that the components were turned off. Driver and receiver enablement from low-power shutdown mode (tPRSH, tPSH, tPRSL, tPSL) takes longer than it does from driver/receiver-disable mode (tPRZH, tPZH, tPRZL, tPZL). SP3485 ApplicationsIndustrial CommunicationAutomotive industryMulti-node communication SP3485 packaging informationSP3485 packaging information SP3485 FAQWhat is the SP3485?The SP3485 is a half-duplex, low-power RS-485 transceiver that operates on 3.3V and fully complies with TIA/EIA-485 standards.

It has a greater sample rate, is less costly, and is smaller in size. The DHT11 has a sampling rate of 1Hz, or one reading every second, whereas the DHT22 has a sampling rate of 0.5Hz, or one reading every two seconds.DHT11 VS DHT22However, the maximum current consumed during conversion (when requesting data) is 2.5mA, whereas the operational voltage of both sensors ranges from 3 to 5 volts. The nice part is that DHT11 and DHT22 sensors can be "swapped"; that is, if you create your project using one, you can simply unplug it and use another. DHT11 and DHT22 ApplicationsMeasure temperature and humidityLocal Weather stationAutomatic climate controlEnvironment monitoring Differences between DHT11 Sensor and ModuleYou can buy the DHT11 sensor as a sensor or as a module. In either case, the sensor's performance is unchanged. The module will have three pins as shown above, whereas the sensor will come in a 4-pin package of which only three pins will be used.The main distinction between the sensor and module is that the module will come with an internal pull-up resistor and filtering capacitor, whereas the sensor requires you to utilize them externally if necessary. DHT11 Sensor Connection to an ArduinoIt is simple to connect DHT sensors to Arduino. They may be simply connected into any breadboard because to their relatively lengthy 0.1′′-pitch pins. Connect the GND pin to the ground and the VCC pin to the Arduino's 5V supply. The Data pin should then be connected to digital pin #8.Wiring DHT11 to Arduino UNOYou must additionally add a 10K pull-up resistor between the Data line and VCC to ensure effective connection between the sensor and MCU (to keep the signal HIGH). There is already a pull-up resistor on the breakout board for the sensor, so you do not need to add another one. Applications for DHT11 SensorsA typical temperature and humidity sensor is the DHT11. The sensor includes a dedicated NTC for temperature measurement and an 8-bit microprocessor for serial data output of temperature and humidity information. Additionally factory calibrated, the sensor makes it simple to integrate with other microcontrollers.The sensor has an accuracy of 1°C and 1% and can measure temperature from 0°C to 50°C and humidity from 20% to 90%. Therefore, if you want to measure in this range, this sensor might be the best option. How to use DHT11 SensorThe DHT11 Sensor produces serial data and is fully calibrated, making setup incredibly simple. Below is a diagram of how this sensor is connected.DHT11 Connection DiagramAs you can see the data pin is connected to an I/O pin of the MCU and a 5K pull-up resistor is used. This data pin outputs the value of both temperature and humidity as serial data. If you are trying to interface DHT11 with Arduino then there are ready-made libraries for it which will give you a quick start.As you can see, a 5K pull-up resistor is being utilized to connect the data pin to an MCU I/O pin. Temperature and humidity values are output as serial data on this data pin. There are pre-made libraries for it that will give you a head start if you're trying to interface DHT11 with Arduino.The datasheet provided below will be useful if you're trying to interface it with another MCU. The data pin's output will be in the following order: 8 bits of humidity integer data, 8 bits of humidity decimal data, 8 bits of temperature integer data, 8 bits of temperature fractional data, and 8 bits of parity bit. The I/O pin must be briefly brought low and then held high as illustrated in the timing diagram below to instruct the DHT11 module to communicate these data:Timing Diagram DHT11 DatasheetDHT11 Datasheet DHT11 FAQAre DHT11 and DHT22 interchangeable?The DHT11 is a little bit more compact and less expensive than the DHT22. These sensors have the advantage of being interchangeable, so you can simply swap a DHT11 for a DHT22 or vice versa. Where is DHT11 sensor used?This sensor is employed in a number of applications, including the measurement of temperature and humidity levels in HVAC systems. These sensors are also used by weather stations to forecast the weather. In houses where residents are susceptible to the effects of humidity, the humidity sensor is employed as a preventative measure. How accurate is the DHT11?Additionally, the DHT11 humidity range is from 20 to 80% with 5% accuracy, but the DHT22 sensor's humidity measuring range is from 0 to 100% with 2-5% accuracy. How does a DHT sensor work?Digital temperature and humidity sensors known as DHTs are inexpensive. There is no need for analog input pins because they measure the surrounding air using a capacitive humidity sensor and a thermistor and communicate a digital signal to the host on the data pin. DHT11, DHT21, and DHT22 sensors are supported by RepRapFirmware as of version 1. 20. Is DHT11 better than DHT22?In every way, including temperature range, temperature accuracy, humidity range, and humidity accuracy, the DHT22 is superior to the DHT11. The DHT22's only drawback is, of course, its slightly greater price, but you are getting better specs for your money.

The LM3481MM/NOPB can be operated at very high switching frequencies to reduce the overall solution size. The switching frequency of the LM3481MM/NOPB can be adjusted to any value between 100kHz and 1MHz by using a single external resistor or by synchronizing it to an external clock.2. What is the difference between DC-DC Switching "Controllers," "Regulators," and "Converters"?They are far more difficult to extinguish and can cause significant damage. Firstly, switching regulators and switching controllers are very similar and serve the same purpose. They are both DC to DC converters. Consider the LM3481MM/NOPB, the switching function is performed outside of the chip by switching controllers. Because the controllers do not have to handle the current, this allows for much higher currents than switching regulators. While switching regulator integrated circuits (ICs) house all of the necessary hardware, with the exception of an inductor and a few resistors and capacitors, on a single chip. The switch mode FET is housed within the regulator. As a result, these chips cannot handle the excessive current.3. Why is it important to know the frequency of the LM3481MM/NOPB? Frequencies are typically in the 50kHz to 500kHz range. These frequencies are either fixed or variable depending on the power supply topology. The LM3481MM/NOPB frequencies can be adjustable typically to any value between 100kHz and 1MHz range.

The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCn/SDn channel or combination of channels can be selected, determined by the contents of the programmable control register. These downstream channels can be used to resolve I²C slave address conflicts. For example, if eight identical digital temperature sensors are needed in the application, one sensor can be connected at each channel: 0-7.The system master can reset the TCA9548A in the event of a time-out or other improper operation by asserting a low in the RESET input. Similarly, the power-on reset deselects all channels and initializes the I²C/SMBus state machine. Asserting RESET causes the same reset and initialization to occur without powering down the part. This allows recovery should one of the downstream I²C buses get stuck in a low state. The pass gates of the switches are constructed sothat the VCC pin can be used to limit the maximum high voltage, which is passed by the TCA9548A. Limiting the maximum high voltage allows the use of different bus voltages on each pair, so that 1.8-V, 2.5-V or 3.3-V parts can communicate with 5-V parts, without any additional protection. External pullup resistors pull the bus up to the desired voltage level for each channel. All I/O pins are 5-V tolerant.  TCA9548APWR Features 1-to-8 Bidirectional translating switchesI²C Bus and SMBus compatibleActive-low reset inputThree address pins, allowing up to eight TCA9548A devices on the I²C busChannel selection through an I²C Bus, in any combinationPower up with all switch channels deselectedLow RON switchesAllows voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V busesNo glitch on power upSupports hot insertionLow standby currentOperating power-supply voltage range of 1.65 V to 5.5 V5-V Tolerant inputs0- to 400-kHz Clock frequencyLatch-up performance exceeds 100 mA Per JESD 78, class II  TCA9548APWR Simplified Application Diagram  TCA9548APWR CAD ModelsSymbolFootprint3D Models                                     TCA9548APWR Pin Configuration and FunctionsPin NamePin NumberTypeDescriptionA01IAddress input 0.
