Non-Volatile Digital Potentiometers feature SPI interface.

Press Release Summary:




Specified over -40 to +125°C range, models MCP4141/2, MCP4241/2, MCP4161/2, and MCP4261/2 can be controlled digitally through SPI interface. All 7- and 8-bit devices feature non-volatile memory for retaining settings at power down, and maximum static current consumption of 5 µA helps extend battery life. Depending on model, packaging options include 8-pin, 3 x 3 mm, DFN, MSOP, PDIP and SOIC; 10-pin MSOP; 10-pin, 4 x 4 mm QFN; and 14-pin SOIC, PDIP, TSSOP packages.

Microchip Technology Introduces Non-Volatile Digital Potentiometers with SPI Interface



7- and 8-bit Devices Are Specified Over Extended Industrial Temperature Range

CHANDLER, Ariz., Oct. 16, 2007 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the MCP4141/2, MCP4241/2, MCP4161/2 and MCP4261/2 (MCP41XX/42XX) non-volatile digital potentiometers. The 7- and 8-bit devices have a 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, maximum, helps to extend battery life.

"We are pleased to expand our mixed-signal product portfolio with the MCP41XX/42XX digital potentiometers," said Bryan Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "Designers can now benefit from using Microchip's low-power digital potentiometers over the popular SPI interface."

"The MCP41XX/42XX family enables designers to enjoy the numerous benefits associated with digital potentiometers in an affordable way," said John Austin, senior product marketing manager with Microchip's Analog and Interface Products Division. "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.
