Overview
The AD660ANZ is a 16-bit monolithic digital-to-analog converter (DAC) produced by Analog Devices Inc. It is part of the DACPORT family and features an on-board voltage reference, double-buffered latches, and an output amplifier. This device is manufactured using the BiMOS II process, which allows for the integration of low power CMOS logic and high precision bipolar linear circuitry on the same chip. The AD660ANZ is highly versatile, supporting both serial and byte input modes, and is designed to minimize data skew errors and facilitate simultaneous updating of DACs in multi-DAC systems.
