Microchip Technology MCP434X and MCP436x quad digital potentiometers are 7- and 8-bit, non-volatile devices featuring an SPI interface and static current consumption of just 5 microamperes (max). The Microchip Technology MCP434X and MCP436X are unlike mechanical potentiometers in that they can be controlled digitally, eliminating the need for human interaction and increasing system accuracy, flexibility, and manufacturing throughput while decreasing manufacturing costs. The non-volatile memory in these Microchip Technology digital potentiometers enables the devices to retain their settings at power down. Their low static current consumption of just 5 microamperes (max) helps extend battery life. The MCP434X and MPC436X are available in space-saving packages as small as 4mm X 4mm QFN, making them ideal for a variety of consumer and industrial applications.
