Description
The MCP41XX and MCP42XX devices offer a wide
range of product offerings using an SPI interface. This
family of devices support 7-bit and 8-bit resistor
networks, Non-Volatile memory configurations, and
Potentiometer and Rheostat pinouts.
WiperLock Technology allows application-specific
calibration settings to be secured in the EEPROM.
