The AD5761R-EP is a single-channel, 16-bit serial input, voltage output, digital-to-analog converter (DAC). It operates from single-supply voltages from 4.75 V to 30 V VDD 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 an easy to use, universal solution.

The device offers guaranteed monotonicity, integral nonlinearity (INL) of ±8 LSB maximum, 35 nV/√Hz noise, and a 7.5 μs settling time on selected ranges.

The AD5761R-EP uses a serial interface that operates at clock rates of up to 50 MHz and is compatible with digital signal processor (DSP) and microcontroller interface standards. Double buffering allows the asynchronous updating of the DAC output. The input coding is user selectable, twos complement or straight binary. The asynchronous reset function resets all registers to their default state. The output range is user selectable via the RA[2:0] bits in the control register.

The device is available in a 16-lead TSSOP package, and it offers guaranteed specifications over the −55°C to +125°C military temperature range.
