The CAT522 is a dual, 8-bit digitally-programmable potentiometer (DPPTM) 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 selfcalibrating systems and for applications where equipment which requires periodic adjustment is either difficult to access or in a hazardous environment.
