The Microchip’s 7- and 8-bit, non-volatile devices feature an SPI interface and static current consumption of just 5 microamperes (max.). They are specified for operation from – 40° C to 125° C and are available in space-saving packages as small as 4 mm x 4 mm QFN, making them ideal for consumer and industrial applications, such as power-supply trim and calibration, set-point and process control, closed-loop servo control, PC peripherals, portable instrumentation, instrumentation offset adjust and signal conditioning.

Unlike mechanical potentiometers, the MCP434X/436X devices can be controlled digitally, through a SPI interface. This eliminates the need for human interaction, which increases system accuracy, flexibility and manufacturing throughput while decreasing manufacturing costs. Digital control also provides more system flexibility than mechanical control. Non-volatile memory enables the digital potentiometers to retain their settings at power down, and their low static current consumption of just 5 microamperes (max.) helps to extend battery life.
