Non-volatile digital potentiometers

14 November 2007 Analogue, Mixed Signal, LSI

The new MCP4141/2 and MCP4241/2 from Microchip are 7-and 8-pin non-volatile digital potentiometers, respectively. They have an SPI interface and are specified over an extended temperature range of -40°C to +125°C. Unlike mechanical potentiometers, the MCP41XX/42XX devices can be controlled digitally, via the SPI interface. This can increase system accuracy, flexibility and manufacturing throughput, while decreasing manufacturing costs. Non-volatile memory enables the devices to retain their settings at power down, and their low static current consumption of just 5 μA maximum helps to extend battery life. These potentiometers are ideal for a wide range of trimming, calibration, set-point, offset-adjust, signal conditioning and control applications. The MCP4141/2 are available in 8-pin SOIC, MSOP, PDIP and 3 mm x 3 mm DFN packages. The MCP4241 is available in 14-pin SOIC, PDIP and TSSOP packages, and a 10-pin 4 mm x 4 mm QFN package. The MCP4242 is available in a 10-pin MSOP and an 8-pin 3 mm x 3 mm DFN package.
