MCP414x/416x/424x/426x Digital Potentiometers
The Microchip MCP413x, MCP415x, MCP423x and MCP425x range of devices are Digital Potentiometers with a SPI interface and EEPROM memory.
Featured is WiperLock Technology, providing a method of ’locking’ the wiper configuration. To unlock a high-voltage command is required (>8.5 V), protecting the setting during normal operation.
7-bit (129 steps) and 8-bit (257 steps) versions are available in various RAB resistance options from 5 kΩ to 100 kΩ. Further variants also give the choice between Rheostat and Potentiometer pinouts, Single and Dual Resistor Network options are also available.
