16-Bit Low Power

DIGITAL-TO-ANALOG CONVERTER

FEATURES

APPLICATIONS

● 16-BIT MONOTONICITY GUARANTEED

● PROCESS CONTROL

OVER –40°C TO +85°C

● ATE PIN ELECTRONICS

● CLOSED-LOOP SERVO-CONTROL

● SMART TRANSMITTERS

● PORTABLE INSTRUMENTS

● VCO CONTROL

● MAX LINEARITY ERROR: 30ppm

● ON-CHIP CALIBRATION

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.

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 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.
