Product DetailsThe AD5722R/AD5732R/AD5752R are dual, 12-/14-/16-bit, serial input, voltage output digital-to-analog converters. They operate from single supply voltages of +4.5 V up to +16.5 V or dual supply voltages from ±4.5 V up to ±16.5 V. Nominal full-scale output range is software selectable from +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V. Integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry are also provided.
The parts offer guaranteed monotonicity, integral nonlinearity (INL) of ±16 LSB maximum, low noise, 10 μs maximum settling time, and an on-chip +2.5 V reference.
The AD5722R/AD5732R/AD5752R use a serial interface that operates at clock rates up to 30 MHz and are compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is user-selectable twos complement or offset binary for a bipolar output (depending on the state of Pin BIN/2sComp), and straight binary for a unipolar output. The asynchronous clear function clears all DAC registers to a user-selectable zero-scale or midscale output. The parts are available in a 24-lead TSSOP and offer guaranteed specifications over the −40°C to +85°C industrial temperature range.

Tools & Simulations
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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
