GENERAL DESCRIPTION
The AD5761/AD5721 are single channel, 16-/12-bit serial input,
voltage output, digital-to-analog converters (DACs). They operate
from single supply voltages from 4.75 V to 30 V or dual supply
voltages from −16.5 V to 0 V VSS and 4.75 V to 16.5 V VDD. The
integrated output amplifier and reference buffer provide a very
easy to use, universal solution.
The devices offer guaranteed monotonicity, integral nonlinearity
(INL) of ±2 LSB maximum, 35 nV/√Hz noise, and 7.5 µs settling
time on selected ranges.
The AD5761/AD5721 use a serial interface that operates at
clock rates of up to 50 MHz and are compatible with DSP and
microcontroller interface standards. Double buffering allows
the asynchronous updating of the DAC output. The input
coding is user-selectable twos complement or straight binary.
The asynchronous reset function resets all registers to their
default state. The output range is user selectable, via the
RA[2:0] bits in the control register.
The devices available in the 16-lead TSSOP and in the 16-lead
LFCSP offer guaranteed specifications over the −40°C to +125°C
industrial temperature range.
