GENERAL DESCRIPTION

The 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 devices 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.
