8-Bit, 165MSPS SpeedPlus(TM) DAC Scalable Current Outputs Between 2mA To 20mA

The DAC908 is a high-speed, digital-to-analog Converter (DAC) offering an 8-bit resolution option within the SpeedPlus family of high-performance converters. Featuring pin compatibility among family e7e members, the DAC900 DAC902 and DAC904 provide a component selection option to an 10-, 12-, and 14-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 DAC908 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 DAC908 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 DAC908 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 DAC908 a power-down mode results in only 45mW of standby power.
The DAC908 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 DAC908.
The reference structure of the DAC908 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 2mA to 20mA, with one external resistor, while maintaining the specified dynamic performance.
The DAC908 is available in the SO-28 and TSSOP-28 packages.
