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 settling time on selected ranges. The AD5761R/AD5721R use a serial interface that operates at clock rates of up to 50 MHz and are compatible with 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 devices available in a 3 mm × 3 mm LFCSP package and a 16-lead TSSOP package offer guaranteed specifications over the −40°C to +125°C industrial temperature range.
