The AD5761R/AD5721R are single channel, 16-/12-bit serialinput, 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.
The devices offer guaranteed monotonicity, integral nonlinearity(INL) of ±2 LSB maximum, 35 nV/√Hz noise, and 7.5 μs settlingtime on selected ranges.The AD5761R/AD5721R use a serial interface that operates atclock rates of up to 50 MHz and are compatible with DSP andmicrocontroller interface standards. Double buffering allows theasynchronous updating of the DAC output. The input codingis user-selectable twos complement or straight binary. Theasynchronous reset function resets all registers to their defaultstate. The output range is user selectable, via the RA[2:0] bitsin the control register.The devices available in a 3 mm × 3 mm LFCSP package and a16-lead TSSOP package offer guaranteed specifications over the−40°C to +125°C industrial temperature range.Feature
