Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the MCP4131/2, MCP4231/2, MCP4151/2 and MCP4251/2 (MCP41/423X and MCP41/425X) digital potentiometers. The volatile, 7- and 8-bit devices have a SPI interface and are specified over the entire extended temperature range of -40 to 125 degrees Celsius. They feature a low static current consumption of just 1 microampere, maximum, and help extend battery life in a variety of consumer and industrial electronic applications.
Unlike their mechanical counterparts, the volatile MCP41/423X and MCP41/425X potentiometers can be controlled digitally, through an SPI interface. This eliminates the need for human interface in order to adjust the wiper setting, which therefore increases system accuracy, flexibility and manufacturing throughput, while decreasing manufacturing costs. The new devices complement the recently announced non-volatile MCP4141/2, MCP4241/2, MCP4161/2 and MCP4261/2 devices, meaning Microchip now provides a comprehensive portfolio of 7- and 8-bit volatile and non-volatile SPI digital potentiometers.
“With MCP41/423X and MCP41/425X devices, Microchip has created another family of low-power digital potentiometers that complement industry trends toward higher-performing devices, in smaller sizes and at lower costs,” said Bryan Liddiard, vice president of marketing with Microchip’s Analog and Interface Products Division.
John Austin, senior product marketing manager with Microchip’s Analog and Interface Products Division, continued, “With extended temperature range operation and availability in several industry-standard packages, we expect the MCP41/423X and MCP41/425X to help designers meet and exceed demands for smaller, better and less-expensive designs.”
The following table lists device-specific features:
|Part #||# of POTs||(Single or Dual)||Resolution Wiper Configuration|
With low static current consumption of only 1 microampere, maximum, the MCP41/423X and MCP41/425X digital potentiometers are appropriate for consumer and industrial electronic 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.
