General Description

DCOM (MSB) DB15 16-Bit, 30 MSPS D/A Converter AD768 FUNCTIONAL BLOCK DIAGRAM VDD AD768 MSBs: SEGMENTED CURRENT SOURCES AND SWITCHES MSB DECODER AND EDGETRIGGERED BIT LATCHES LSBs: CURRENT SOURCES, SWITCHES, AND 1kΩ R-2R LADDERS IOUTA IOUTB 1k 1k LADCOM DB0 (LSB) CLOCK NC 2.5V BANDGAP REFERENCE CONTROL AMP VEE REFCOM REFOUT IREFIN NR The AD768 is a 16-bit, high speed digital-to-analog converter (DAC) that offers exceptional ac and dc performance.

The AD768 is manufactured on ADI’s Advanced Bipolar CMOS (ABCMOS) process, combining the speed of bipolar transistors, the accuracy of laser-trimmable thin film resistors, and the efficiency of CMOS logic.

A segmented current source architecture is combined with a proprietary switching technique to reduce glitch energy and maximize dynamic accuracy.
