In single converter applications, the serial interface can
be accomplished with just two wires, allowing lowcost isolation. For multiple converters, a CS signal
allows for selection of the appropriate D/A converter. The DAC1221 is a Digital-to-Analog (D/A) converter
offering 16-bit monotonic performance over the specified temperature range. It utilizes delta-sigma technology 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. XIN XOUT 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 applications, battery-powered instruments, and isolated systems. The DAC1221 is available in a SSOP-16 package. C1 C2A C2B C3 VREF Clock Generator
