IC/Module: MCP4161 8-bit Single-Channel Digital POT
MCP4161 is a non-volatile, single-channel digital potentiometer with 8-bit register network resolution. It uses SPI compatible interface and is useful for devices that need factory trimming or recalibration. With WiperLock Technology, this module allows automatic recall of potentiometer wiper settings.
Power Supply Selection
DIGI POT Click Board™ is designed to operate using a 3.3V or 5V power supply. It is soldered in 3.3V position by default. However, the on-board PWR SEL zero-ohm SMD jumper can be resoldered to 5V position if it is to be used with 5V development system.
