The DAC7644 is a 16-bit, quad voltage output digital-to-analog converter with guaranteed 15-bit monotonic performance over the specified temperature range. It accepts 16-bit parallel input data, has double-buffered DAC input logic (allowing simultaneous update of all DACs), and provides a readback mode of the internal input registers. Programmable asynchronous reset clears all 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 DAC7644 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7644 is available in a 48-lead SSOP package and offers guaranteed specifications over the –40°C to +85°C temperature range.
