Microchip Technology  a provider of microcontroller and analog semiconductors, has announced the MCP4141/2, MCP4241/2, MCP4161/2 and MCP4261/2 (MCP41XX/42XX) non-volatile digital potentiometers. The new 7- and 8-bit devices have an SPI interface and are specified over the extended industrial temperature range of -40 to 125 degrees Celsius. They are available in several industry-standard packages, including the popular 3 mm x 3 mm DFN package.

Unlike mechanical potentiometers, the MCP41XX/42XX devices can be controlled digitally, through an SPI interface. This increases 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 microamperes (µA), maximum, helps to extend battery life.

The MCP41XX/42XX family enables designers to enjoy the numerous benefits associated with digital potentiometers in an affordable way. With extended temperature range operation and availability in many industry-standard packages, the devices are expected to help designers meet and exceed demands for smaller, better and less-expensive designs.

The MCP41XX/42XX digital potentiometers are well suited for a wide variety of 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.

Packaging and availability:

  • MCP4141/2:8-pin SOIC, MSOP, PDIP and 3 mm x 3 mm DFN packages
  • MCP4241: 10-pin 4 mm x 4 mm QFN package, 14-pin SOIC, PDIP, TSSOP packages
