DESCRIPTION

The CAT504 is a quad 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, it is also well suited for systems capable of self calibration, and applications where equipment which is either difficult to access or in a hazardous environment, requires periodic adjustment.

FEATURES

■ Output settings retained without power

■ Output range includes both supply rails

■ 4 independently addressable outputs

■ 1 LSB Accuracy

■ Serial µP interface

■ Single supply operation: 2.7V-5.5V

■ Setting read-back without effecting outputs

APPLICATIONS

■ Automated product calibration.

■ Remote control adjustment of equipment

■ Offset, gain and zero adjustments in Self-Calibrating and Adaptive Control systems.

■ Tamper-proof calibrations.
