DESCRIPTION
The CAT522 is a dual 8-Bit Memory DAC designed as an electronic replacement for mechanical potentiometers and trim pots. Intended for final calibration of products such as camcorders, fax machines and cellular telephones on automated high volume production lines and systems capable of self calibration, it is also well suited for applications were equipment requiring periodic adjustment is either difficult to access or located in a hazardous environment.

FEATURES
■ Buffered Outputs
■ Output settings retained without power
■ Independent Reference Inputs
■ Output range includes both supply rails
■ Programming voltage generated on-chip
■ 2 independently addressable outputs
■ Serial µP interface
■ Single supply operation: 2.7V-5.5V

APPLICATIONS
■ Automated product calibration.
■ Remote control adjustment of equipment
■ Offset, gain and zero adjustments in Sel-Calibrating and Adaptive Control systems.
■ Tamper-proof calibrations.
