DESCRIPTION
The DAC1221 is a Digital-to-Analog (D/A) converter
offering 16-bit monotonic performance over the speci-
fied temperature range. It utilizes delta-sigma technol-
ogy to achieve inherently linear performance in a
small package at very low power. The output range is
two times the external reference voltage. On-chip
calibration circuitry dramatically reduces offset and
gain errors.
The DAC1221 features a synchronous serial interface.
In single converter applications, the serial interface can
be accomplished with just two wires, allowing low-
cost isolation. For multiple converters, a CS signal
allows for selection of the appropriate D/A converter.
The DAC1221 has been designed for closed-loop
control applications in the industrial process control
market, and high resolution applications in the test and
measurement market. It is also ideal for remote appli-
cations, battery-powered instruments, and isolated sys-
tems.
The DAC1221 is available in a SSOP-16 package.
