Description
General part information
DAC908 Series
The DAC908 is a high-speed, Digital-to-Analog Converter (DAC) offering an 8-bit resolution option within theSpeedPlusfamily of high-performance converters. Featuring pin compatibility among family 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.
