CAT521WI-TE13

Configured Digitally Programmable Potentiometer DPP™: Programmable Voltage Applications

DESCRIPTION

The CAT521 is a 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

■8-bit DPP configured as a programmable voltage source in DAC-like applications

■Buffered wiper output

■Non-volatile NVRAM memory wiper storage

■Output voltage range includes both supply rails

■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
