Microchip Technology
Description
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.
