The DAC7624 and DAC7625 are 12-bit quad voltage output digital-to-analog converters with guaranteed 12-bit monotonic performance over the specified temperature range. They accept 12-bit parallel input data, have double-buffered DAC input logic (allowing simultaneous update of all DACs), and provide a readback mode of the internal input registers. An asynchronous reset clears all registers to a mid-scale code of 800H (DAC7624) or to a zero-scale of 000H (DAC7625). The DAC7624 and DAC7625 can operate from a single +5V supply or from +5V and –5V supplies. Low power and small size per DAC make the DAC7624 and DAC7625 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7624 and DAC7625 are available in a 28-pin plastic double-wide or a 28-lead SOIC package, and offer guaranteed specifications over the –40°C to +85°C temperature range.
The DAC7624 and DAC7625 are 12‑bit quad voltage‑output digital‑to‑analog converters offering low‑power operation, unipolar or bipolar output ranges, and built‑in data read‑back. They are intended for automatic test equipment, DAC‑per‑pin programmers, data‑acquisition systems, process control, and closed‑loop servo applications.
The datasheet includes feature highlights, absolute maximum ratings, detailed pin descriptions, typical performance curves, package options (28‑pin DIP or 28‑lead SOIC), and ordering information. It also contains regulatory and warranty notices from Texas Instruments.
