The DAC7744 is a 16-bit, quad voltage output digital-to-analog converter with guaranteed 16-bit monotonic performance over the specified temperature range. It is ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control.
The DAC7744 provides four independent voltage outputs with 16‑bit resolution. It operates from either a single +15 V supply or dual ±10 V supplies, offering both unipolar and bipolar output ranges. Features include low power consumption (200 mW), programmable reset to mid‑scale or zero‑scale, data read‑back, and double‑buffered inputs for simultaneous updates.
Typical specifications cover accuracy, monotonicity, settling time, output current (5 mA per channel), and load capacitance (500 pF). The device is supplied in a 48‑lead SSOP package and is rated for –40 °C to +85 °C operation. Detailed pin descriptions, absolute maximum ratings, and typical performance curves are provided.
