DESCRIPTION
The DAC7644 is a 16-bit, quad voltage output digital-to-analog converter with guaranteed 15-bit monotonicperformance over the specified temperature range. Itaccepts 16-bit parallel input data, has double-bufferedDAC input logic (allowing simultaneous update of allDACs), and provides a readback mode of the internalinput registers. Programmable asynchronous reset clearsall registers to a mid-scale code of 8000H or to a zero-scale of 0000H. The DAC7644 can operate from a single+5V supply or from +5V and –5V supplies.Low power and small size per DAC make the DAC7644ideal for automatic test equipment, DAC-per-pin pro-grammers, data acquisition systems, and closed-loopservo-control. The DAC7644 is available in a 48-lead
SSOP package and offers guaranteed specificationsover the –40°C to +85°C temperature range.
