The DAC902 is a high-speed, Digital-to-Analog Converter (DAC) offering a 12-bit resolution option .The DAC902 support updaterates 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 DAC902 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 close matching of the current outputs ensures superior dynamic performance in the differential configuration. Its low power consumption allows for use in portable and batteryoperated systems. Further optimization can be realized by lowering the output current with the adjustable full-scale option.Generally, it can be used in digital microwave links, cable modems, arbitrary waveform generation, high-speed instrument control, video and digital TV.
