The AD569 is a 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices, which has the characteristics of 16-bit monotonicity, low power consumption, and low noise. It is suitable for applications such as robots, closed-loop positioning, high-precision ADCs, and microprocessor-based process control.
The AD569 is a monolithic 16‑bit digital‑to‑analog converter fabricated in Analog Devices’ BiMOS II process. Its voltage‑segmented architecture guarantees monotonicity over temperature and provides a typical settling time of 3 ps to 0.001 % of full scale. The device supports both unipolar and bipolar reference inputs and can be loaded from 8‑ or 16‑bit buses.
The converter is offered in several grades (J, K, AD, BD, SD) with operating temperature ranges from –55 °C to +125 °C and packaged in 28‑pin plastic DIP, PLCC or ceramic DIP. It includes on‑chip buffer amplifiers capable of driving a 1 kΩ load or 1000 pF capacitive load, and features ESD protection suitable for MIL‑STD‑883 applications.
