DESCRIPTION

The CAT524 is a quad, 8-bit digitally-programmable potentiometer (DPP?) configured for programmable voltage and DAC-like applications. 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 self-calibrating systems and for applications where equipment which requires periodic adjustment is either difficult to access or in a hazardous environment.

FEATURES

■ Four 8-bit DPPs configured as programmable voltage sources in DAC-like applications

■ Common reference inputs

■ Buffered wiper outputs

■ Non-volatile NVRAM memory wiper storage

■ Output voltage range includes both supply rails

■ 4 independently addressable buffered output wipers

■ 1 LSB accuracy, high resolution

■ Serial Microwire-like 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

■ DAC (with memory) substitute
