Product Summary

The DAC7725U is a 12-bit quad voltage output digital-to-analog converter with guaranteed 12-bit monotonic performance over the specified temperature range. The device accepts 12-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. An asynchronous reset clears all registers to a zero-scale of 000H. The DAC7725U can operate from a single +15V supply, or from +15V and –15V supplies. The applications of the DAC7725U include process control, closed-loop servo-control, motor control and data acquisition systems.
