GENERAL DESCRIPTION

The AD5761R/AD5721R are single channel, 16-/12-bit serial input, voltage output, digital-to-analog converters (DACs). They operate from single supply voltages from +4.75 V to +30 V or dual supply voltages from −16.5 V to 0 V VSS and +4.75 V to +16.5 V VDD. The integrated output amplifier, reference buffer, and reference provide a very easy to use, universal solution.
