Product Summary

The AD569BD 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 AD569BD chip includes two resistor strings, selector switches decoding logic, buffer amplifiers, and double-buffered input latches. The AD569BD’s voltage-segmented architecture insures 16-bit monotonicity over time and temperature. Integral nonlinearity is maintained at ±0.01%, while differential nonlinearity is ±0.0004%. The on-chip, high-speed buffer amplifiers provide a voltage output settling time of 3 ms to within ±0.001% for a full-scale step.
