DAC902E

The DAC902E is a high-speed 12-bit Digital-to-analog Converter (DAC) offering a resolution option within the SpeedPlus Family of high-performance converters. 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 DAC902 has a high impedance 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 DAC902 can be operated on a wide, single-supply range of 2.7 to 5.5V. Its low power consumption allows for use in portable and battery-operated systems.
