MICROCHIP MCP4662-103E/UN

The MCP45XX and MCP46XX devices offer a wide range of product offerings using an I²C interface. This family of devices support 7-bit and 8-bit resistor networks, nonvolatile memory configurations, and Potentiometer and Rheostat pinouts. WiperLock Technology allows application-specific calibration settings to be secured in the EEPROM.
