The DAC904 is a high-speed, Digital-to-Analog Converter (DAC) offering a 14-bit resolution option within the family of high-performance converters. Featuring pin compatibility among family members, the DAC908, DAC900, and DAC902 provide a component selection option to an 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 (200k) current output with a nominal range of 20mA and an output compliance of up 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 of +2.7V to +5.5V. Its low power consumption allows for use in portable and 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.
