The AD569SE/883B is a monolithic 16-bit digital-to-analog converter (DAC) manufactured using Analog Devices’ BiMOS II process. This component integrates two resistor strings, selector switches, decoding logic, buffer amplifiers, and double-buffered input latches on a single chip. It features guaranteed 16-bit monotonicity and low drift characteristics. The device supports 8- and 16-bit bus compatibility and includes voltage output buffers. It is designed for high-precision applications requiring stable analog signal generation from digital inputs.
The AD569SE/883B belongs to the AD569 family of 16-bit DACs. The suffix 'SE' typically denotes space-grade or enhanced screening, while '/883B' indicates compliance with MIL-STD-883 standards for microcircuits. This variant is specifically tailored for military and aerospace environments where reliability and radiation tolerance are critical requirements.
Direct replacements must match the 16-bit resolution, parallel interface, and dual-supply operation. Verify that substitute components meet MIL-STD-883 qualification if the application requires it. Standard commercial grade AD569 variants may not offer the same environmental robustness.
