20-Bit, Low-Power

Digital-to-Analog Converter

Check for Samples: DAC1220

FEATURES

DESCRIPTION

•

20-Bit Monotonicity Ensured Over –40°C to

+85°C

The DAC1220 is a 20-bit digital-to-analog (D/A)

converter offering 20-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 resolution of the device can be programmed to

20 bits for Full-Scale, settling to 0.003% within 15ms

typical, or 16 bits for Full-Scale, settling to 0.012%

within 2ms max. The output range is two times the

external reference voltage. On-chip calibration

circuitry dramatically reduces low offset and gain

errors.

•

Low Power: 2.5mW

Voltage Output

Settling Time: 2ms to 0.012%

Maximum Linearity Error: ±0.0015%

On-Chip Calibration

APPLICATIONS

•

Process Control

ATE Pin Electronics

Closed-Loop Servo Control

Smart Transmitters

Portable Instruments

The DAC1220 features

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 DAC1220 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 DAC1220 is available in an

SSOP-16 package.
