Non-Volatile Digital Potentiometers with SPI Interface
Microchip Technology Inc. announced its MCP4141/2, MCP4241/2, MCP4161/2 and MCP4261/2 non-volatile digital potentiometers. The 7- and 8-bit devices have an SPI interface, and they are specified over the extended industrial temperature range of -40°C to 125°C. They are available in several industry-standard packages, including the 3 mm × 3 mm DFN package. Non-volatile memory enables the devices to retain their settings at power down, and their low static current consumption of 5 mA maximum helps to extend battery life. They are suitable for a 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.
