PRODUCT DESCRIPTION

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. Edge triggered input latches and a temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution.
