Overview
The AD569JN is a 16-bit monolithic digital-to-analog converter (DAC) manufactured by Analog Devices Inc. using their BiMOS II process. This process allows the integration of low power CMOS logic functions and high precision bipolar linear circuitry on the same chip. The AD569JN features a voltage-segmented architecture that ensures 16-bit monotonicity over time and temperature, making it suitable for high-precision applications.
