GENERAL DESCRIPTION

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 devices are available in a 24-lead TSSOP and

offer guaranteed specifications over the −40°C to +85°C

industrial temperature range.
