Potentiometers handle extended temperature range

Digital control can increase system accuracy, flexibility and manufacturing throughput.

Microchip has released the MCP4141/2 and MCP4241/2 nonvolatile digital potentiometers.

The new 7 and 8bit devices have an SPI interface and are specified over an extended temperature range of -40 to +125C.

Unlike mechanical potentiometers, the MCP41XX/42XX devices can be controlled digitally, via an SPI interface.

This can increase system accuracy, flexibility and manufacturing throughput, while decreasing manufacturing costs.

Nonvolatile memory enables the devices to retain their settings at power down and their static current consumption of 5uA maximum helps to extend battery life.

The MCP41XX/42XX digital potentiometers are ideal for a wide range of trimming, calibration, set-point, offset-adjust, signal conditioning and control applications.

The MCP4141/2 digital potentiometers are available in 8-pin SOIC, MSOP, PDIP and 3 x 3mm DFN packages.

The MCP4241 is available in 14-pin SOIC, PDIP and TSSOP packages and a 10-pin 4 x 4mm QFN package.

The MCP4242 is available in a 10-pin MSOP and an 8-pin 3 x 3mm DFN package.
