DESCRIPTION

The CAT525 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 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

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

■ Independent 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
