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 fullscale output range is software-selectable from the options of +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V. Integrated output amplifiers, reference buffers, and proprietary power-up/powerdown 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 patible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is user-selectable twos plement or offset binary for a bipolar output (depending on the state of pin BIN/2sp), and straight binary for a unipolar output. The asynchronous clear function clears all DAC registers to a user-selectable zero-scale or mid-scale output. The parts are available in a 24-lead TSSOP and offer guaranteed...
