Product Details

The AD5724R/AD5734R/AD5754R are quad, 12-/14-/16-bit serial input, voltage output, digital-to-analog converters DACs. 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 typical settling time, and an on-chip +2.5 V reference.

The AD5724R/AD5734R/AD5754R 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 mid-scale output. The parts are available in a 24-lead TSSOP and offer guaranteed specifications over the −40°C to +85°C industrial temperature range.
