The unregulated voltage is provided to pin 1 (Vin) through the filter capacitor to reduce input noise. The ON/OFF or enable pin (pin 5) should be grounded to enable the IC. If set to high level, IC will enter shutdown mode and prevent leakage current. This function is very useful for saving input power when working on battery. The feedback pin is an important pin for setting the output voltage. It detects the output voltage and adjusts the switching frequency of the internal switch according to the value of the output voltage to provide the required output voltage. Finally, the output voltage is obtained through pin 2 through the LC filter. The complete circuit diagram is shown below, and you can usually find these circuits in the LM2596 DC converter module.CAD and CAE SymbolsPackagePinsDownload(NEB)5View optionsDDPAK/TO-263 (KTT)5View optionsTO-220 (NDH)5View optionsAdvantagesThe LM2596 series regulator is a monolithic integrated circuit with all the functions of a step-down switching regulator, capable of driving a 3A load through excellent line and load regulation.

The size of the heat sink is determined by the input voltage, output voltage, load current and ambient temperature. The higher the ambient temperature, the higher the need for heat dissipation.The LM2596 in the TO-263(S) package is a surface mount component to be soldered on the PCB board. Copper and PCB board contribute to the heat dissipation of this packaged device, such as freewheeling diodes and inductors.The copper area on the PCB for soldering this packaged device must be at least 0.4 square inches. More copper area will improve the thermal characteristics, but when it is larger than 6 square inches, the improvement in heat dissipation is very small, so ventilation in the case of use.Product ManufacturerTexas Instruments Inc.

Among them, the sound quality control part uses an attenuated tone circuit controlled separately for high and low sounds. The specific components are as follows:R02, R03, C02, C01, W02 form a bass control circuit ;C03, C04, W03 form a treble control circuit ;R04 is the isolation resistance;W01 is the volume controller, which adjusts the volume of the amplifier;C05 is an isolation capacitor to prevent the downstream LM1875 DC potential element from affecting the previous tone circuit.The amplifying circuit mainly adopts LM1875, which is composed of 1875, R08, R09, C066, etc. The magnification of the circuit is determined by the ratio of R08 to R09; C06 is used to stabilize the drift of the LM1875's 4th pin DC zero potential, but it has a certain impact on the sound quality; C07 and R10 function to prevent the amplifier from generating low-frequency self-excitation. In Addition, the load impedance of this amplifier is 4→16Ω.Figure 2. LM1875 CircuitWhat about the power supply circuit of the power amplifier? Please take a look at the picture below. In order to ensure the sound quality of the power amplifier board, we need to pay attention to the following when designing the circuit:The output power of the power transformer shall not be less than 80W;The output voltage is 2*25V;The filter capacitor uses two 4700UF/25V electrolytic capacitors in parallel;Positive and negative power supplies share 4 4700UF/25V capacitors;The two 104 base capacitors are high-frequency filter capacitors;Figure 3. LM1875 CircuitIV LM1875 Circuit Assembly and DebuggingThis blog will introduce the necessary tools for circuit assembly, how to prepare for soldering, and finally how to debug the circuit. Of course, if you still feel like you are still cannot get enough, in the end, you can even follow our tips to try an extra interesting experiment with this circuit.Tools That You NeedA 20W electric soldering iron, preferably with adjustable temperature;A multimeter;A pair of needle-nose pliers;A screwdriver;Some solder wire and pine perfume.How to Prepare for WeldingWelding sequence:① Welding jumpers;② Welding resistance;③ Welding capacitor;④ Welded rectifier tube;⑤ Welding potentiometer;⑥ Weld LM1875.Notes Fix the LM1875 with screws on the heat sink before welding LM1875, otherwise, the screws will be difficult to drive in when the heat sink is installed at the end;The part of LM1875 in contact with the heat sink must be coated with a small amount of heat dissipation grease to facilitate heat dissipation;Pay attention to the welding quality when welding. For beginners, you can practice a few more times on the old circuit board, and then formally solder.How to Debug CorrectlyThe debugging of this power amplifier board is very simple. After the circuit board is soldered with electronic components, we must carefully check the circuit board for soldering errors. Special attention should be paid to electronic parts with polarity, such as electrolytic capacitors and bridge rectifiers. Once the welding is reversed, there is a risk of burning the components.When the transformer is connected, the output terminal of the amplifier is not connected to the speaker, but connected to a multimeter (preferably digital display, and the multimeter is set to DC*2V).In addition, pay attention to the reading of the multimeter when powering on the power amplifier board. Under normal circumstances, the reading should be within 30mV, otherwise we should immediately cut off the power to check the circuit board.If the reading of the electric meter is within the normal range, it indicates that the function of the power amplifier board is basically normal. At this time, we connected the speaker, then input the music signal, and then power on the test machine. Under the correct procedures and specifications, turn the volume potentiometer, the volume should change, and turn the high and low knobs, the tone of the speaker will change.Figure 4. LM1875Experiment Worth Trying First, we will short-circuit C6 and measure the DC potential at the output of LM1875 with a multimeter to see if it is within 30MV. Then, connect the speaker and test for two hours. Use a multimeter to measure the DC potential at the output of the LM1875 to see if the DC potential is within 30MV. If the DC potential is within 30MV, the capacitor C6 can be omitted. In this case, the amplifier board becomes a pure DC power amplifier.V In the EndSo far, the power amplifier board has been successfully installed and adjusted.

These amplifiers feature low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust, which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner. Video: ENTENDA O SLEW RATE: 741 VERSUS LF356N! CatalogProduct OverviewLF356N FeaturesLF356N ApplicationsLF356N PinoutLF356N ReplacementLF356N CAD ModelsLF356N Schematic DiagramsLF356N Circuit DiagramLF356N Block DiagramLF356N SpecificationLF356N vs LF356N/NOPBLF356N ManufacturerLF356N DatasheetUsing WarningsFAQ LF356N FeaturesReplace Expensive Hybrid and Module FET Op AmpsRugged JFETs Allow Blow-Out Free Handling Compared With MOSFET Input DevicesExcellent for Low Noise Applications Using Either High or Low Source ImpedanceVery Low 1/f CornerOffset Adjust Does Not Degrade Drift or Common-Mode Rejection as in Most Monolithic AmplifiersNew Output Stage Allows Use of Large Capacitive Loads (5,000 pF) Without Stability ProblemsInternal Compensation and Large Differential Input Voltage Capability LF356N ApplicationsPrecision High-Speed IntegratorsFast D/A and A/D ConvertersHigh Impedance BuffersWideband, Low Noise, Low Drit AmplifiersLogarithmic AmplifersPhotocell AmplifersSample and Hold Circuits LF356N PinoutThe following figure is the diagram of LF356N pinout. LF356N Pinout LF356N ReplacementLF356N/NOPB LF356N CAD ModelsFollowings are LF356N Symbol, Footprint, and 3D Model. LF356N Symbol LF356N Footprint LF356N 3D Model LF356N Schematic DiagramsThe architecture of LF356N is shown in the picture below. LF356N Schematic Diagrams LF356N Circuit DiagramFollowing is the circuit diagram of LF356N. LF356N Circuit Diagram LF356N Block DiagramThe following figure shows the block diagram of LF356N. LF356N Block Diagram LF356N SpecificationMaximum Dual Supply Voltage+/- 18 VPSRR - Power Supply Rejection Ratio80 dBIn - Input Noise Current Density0.01 pA/sqrt HzCMRR - Common Mode Rejection Ratio100 dBInput TypeRail-to-RailOperating Supply Current5 mAGBP - Gain Bandwidth Product5 MHzMaximum Operating Temperature+ 70 CNumber of Channels1 ChannelSupply Voltage - Max44 VMinimum Operating Temperature0 CVos - Input Offset Voltage2 mVProduct CategoryOperational Amplifiers - Op AmpsTechnologyBiFETShutdownNo ShutdownSR - Slew Rate12 V/usIb - Input Bias Current200 pASupply Voltage - Min10 VVcm - Common Mode Voltage10 V to 36 Ven - Input Voltage Noise Density12 nV/sqrt HzPackage / CasePDIP-8Mounting StyleThrough HoleProductOperational AmplifiersMinimum Dual Supply Voltage+/- 5 VOutput Current per Channel25 mA LF356N vs LF356N/NOPB  LF356NLF356N/NOPBPart Life Cycle CodeObsoleteTransferredPart Package CodeDIPDIPPackage DescriptionDIP, DIP8,.3DIP, DIP8,.3Pin Count88Reach Compliance Codenot_compliantcompliantECCN CodeEAR99EAR99HTS Code8542.33.00.018542.33.00.01Amplifier TypeOPERATIONAL AMPLIFIEROPERATIONAL AMPLIFIERArchitectureVOLTAGE-FEEDBACKVOLTAGE-FEEDBACKAverage Bias Current-Max (IIB)0.0002 µA0.0002 µABias Current-Max (IIB) @25C0.0002 µA0.0002 µACommon-mode Reject Ratio-Nom100 dB100 dBFrequency CompensationYESYESInput Offset Current-Max (IIO)0.002 µA0.002 µAInput Offset Voltage-Max13000 µA13000 µAJESD-30 CodeR-PDIP-T8R-PDIP-T8JESD-609 Codee0e3Length9.817 mm9.817 mmLow-BiasYESYESLow-OffsetNONOMoisture Sensitivity Level11Neg Supply Voltage Limit-Max-18 V-18 VNeg Supply Voltage-Nom (Vsup)-15 V-15 VNumber of Functions11Number of Terminals88Operating Temperature-Max70°C70°CPackage Body MaterialPLASTIC/EPOXYPLASTIC/EPOXYPackage CodeDIPDIPPackage Equivalence CodeDIP8,.3DIP8,.3Package ShapeRECTANGULARRECTANGULARPackage StyleIN-LINEIN-LINEPacking MethodRAILRAILPeak Reflow Temperature (Cel)NOT SPECIFIED260Power Supplies+-15 V+-15 VQualification StatusNot QualifiedNot QualifiedSeated Height-Max5.08 mm5.08 mmSlew Rate-Nom12 V/us12 V/usSupply Current-Max10 mA10 mASupply Voltage Limit-Max18 V18 VSupply Voltage-Nom (Vsup)15 V15 VSurface MountNONOTechnologyBIPOLARBIPOLARTerminal FinishTin/Lead (Sn/Pb)Matte Tin (Sn)Terminal FormTHROUGH-HOLETHROUGH-HOLETerminal Pitch2.54 mm2.54 mmTerminal PositionDUALDUALTime@Peak Reflow Temperature-Max (s)NOT SPECIFIED40Unity Gain BW-Nom5000 kHz5000 kHzVoltage Gain-Min1500015000Width7.62 mm7.62 mmBase Number Matches41Common-mode Reject Ratio-Min 80 dB LF356N ManufacturerTexas Instruments Incorporated (TI) is a global semiconductor design and manufacturing company that develops analog ICs and embedded processors.
