battery-operated systems. Further optimization can be realized by lowering the output current with the adjustable full-scale option. For noncontinuous operation of the DAC904, a power-down mode results in only 45mW of standby power. The DAC904 comes with an integrated 1.24V bandgap reference and edge-triggered input latches, offering a complete converter solution. Both +3V and +5V CMOS logic families can be interfaced to the DAC904. The reference structure of the DAC904 allows for additional flexibility by utilizing the on-chip reference, or applying an external reference. The full-scale output current can be adjusted over a span of 2-20mA, with one external resistor, while maintaining the specified dynamic performance. The DAC904 is available in SO-28 and TSSOP-28 packages.


DESCRIPTION

The is a high-speed, Digital-to-Analog Converter (DAC) offering a 14-bit resolution option within the family of highperformance converters. Featuring pin compatibility among family members, the DAC908, DAC900, and DAC902 provide a component selection option 8-, 10-, and 12-bit resolution, respectively. All models within this family of DACs support update rates in excess of 165MSPS with excellent dynamic performance, and are especially suited to fulfill the demands of a variety of applications. The advanced segmentation architecture of the DAC904 is optimized to provide a high Spurious-Free Dynamic Range (SFDR) for single-tone, as well as for multi-tone signals-- essential when used for the transmit signal path of communication systems. The DAC904 has a high impedance (200kOhm) current output with a nominal range of 20mA and an output compliance to 1.25V. The differential outputs allow for both a differential or single-ended analog signal interface. The close matching of the current outputs ensures superior dynamic performance in the differential configuration, which can be implemented with a transformer. Utilizing a small geometry CMOS process, the monolithic DAC904 can be operated on a wide, single-supply range to +5.5V. Its low power consumption allows for use in portable and

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
