The DAC902 is a high-speed, Digital-to-Analog Converter (DAC)offering a 12-bit resolution option within the SpeedPlus Family ofhigh-performance converters. Featuring pin compatibility amongfamily members, the DAC908, DAC900, and DAC904 provide acomponent selection option to an 8-, 10-, and 14-bit resolution,respectively. All models within this family of DACs support updaterates in excess of 165MSPS with excellent dynamic performance,and are especially suited to fulfill the demands of a variety ofapplications.The advanced segmentation architecture of the DAC902 is optimizedto provide a high Spurious-Free Dynamic Range (SFDR) forsingle-tone, as well as for multi-tone signals—essential when usedfor the transmit signal path of communication systems.The DAC902 has a high impedance (200kΩ) current output with anominal range of 20mA and an output compliance of up to 1.25V.The differential outputs allow for both a differential or singleendedanalog signal interface. The close matching of the currentoutputs ensures superior dynamic performance in the differentialconfiguration, which can be implemented with a transformer.Utilizing a small geometry CMOS process, the monolithic DAC902can be operated on a wide, single-supply range of +2.7V to +5.5V.Its low power consumption allows for use in portable and batteryoperatedsystems. Further optimization can be realized by loweringthe output current with the adjustable full-scale option.
