Overview
The AD768AR, produced by Analog Devices Inc., is a 16-bit, high-speed digital-to-analog converter (DAC) designed to offer exceptional AC and DC performance. Manufactured using ADI's Advanced Bipolar CMOS (ABCMOS) process, this DAC combines the speed of bipolar transistors, the accuracy of laser-trimmable thin film resistors, and the efficiency of CMOS logic. The AD768AR features a segmented current source architecture and proprietary switching techniques to reduce glitch energy and maximize dynamic accuracy.
