The AD569KNZ is a monolithic 16-bit Digital-to-analog Converter (DAC) manufactured in Analog Devices BiMOS II process. BiMOS II allows the fabrication of low power CMOS logic functions on the same chip as high precision bipolar linear circuitry. The AD569 chip includes two resistor strings, selector switches decoding logic, buffer amplifiers and double-buffered input latches. Its voltage-segmented architecture insures 16-bit monotonicity over time and temperature. The on-chip high-speed buffer amplifiers provide a voltage output settling time of 3μs to within ±0.001% for a full-scale step. The AD569 can operate with an AC reference in multiplying applications. Data may be loaded into the AD569 input latches from 16-bit buses. The double-buffered structure simplifies 8-bit bus interfacing and allows multiple DACs to be loaded asynchronously and updated simultaneously. Four TTL/LSTTL/5V CMOS-compatible signals control the latches: CS, LBE, HBE and LDAC.
