Product Overview
MCP446X family is available with end-to-end resistor values of 5Kohm, 10Kohm, 50Kohm and 100Kohm. These devices offer WiperLock™ technology which allows users unlimited reprogramming and locking of the wiper setting. It is useful for equipment that requires factory trimming or recalibration. The MCP446X devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. Typical applications include medical: test and measurement equipment, industrial applications: power supply, automotive: system calibrations and consumer: audio and tone controls.
