Featuring pin compatibility among family members, the DAC908, DAC900, and DAC904 provide a component selection option to an 8-, 10-, 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 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 (200kΩ) current output with a nominal range of 20mA and an output compliance of up to 1.2...
