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.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.

Evaluation Kits (1)
The EVAL-AD5761RSDZ is a full featured evaluation board that allows the user to easily evaluate all the features of the AD5761R 16-bit, voltage output digital-to-analog converter (DAC). This board also integrates a power solution using the ADP5070 switching regulator to generate a bipolar supply of +11 V and −21 V from a +3.3 V input, allowing any of the programmable DAC voltage output ranges available on the DAC. Alternatively, supplying the DAC with a linear power supply via the on-board connector (J4) achieves all ranges. The AD5761R pins are accessible at on-board connectors for external connection. The evaluation board can be controlled by two means: via the on-board connector (J5), or via the SDP connector (J1). The EVAL-SDP-CB1Z SDP board allows the evaluation board to be controlled through the USB port of a Windows® XP (SP2 or later) or Windows Vista (32-bit) based PC using the AD5761R evaluation software.
The AD5761R is a single channel, 16-bit serial input, voltage output DAC. The device is specified to operate from single supply voltages from 4.75 V up 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 nominal full-scale output range is software or hardware selectable. The integrated output amplifiers, reference buffers, and power-up/power-down control circuitry provide an easy to use, universal solution.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
