Overview
The AD660BRZ, produced by Analog Devices Inc., is a monolithic 16-bit digital-to-analog converter (DAC) that integrates a voltage reference, double-buffered latches, and an output amplifier on a single chip. This device is part of the DACPORT® family and is manufactured using the BiMOS II process, allowing for the combination of low power CMOS logic and high precision bipolar linear circuitry.
The AD660BRZ is highly versatile, offering both serial and byte input modes, and is designed to minimize data skew errors and facilitate simultaneous updating of DACs in multi-DAC systems. It is available in various packages, including the 24-lead SOIC package for the BRZ version.
