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.
