Microchip Creates Low-power, 6-bit, Volatile Digital Potentiometers

2/27/2006 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced a new family of low-power, low-voltage, 6-bit digital potentiometers. The MCP4011 MCP4014 digital potentiometers provide engineers with a digitally controlled solution that is cost- and size- competitive with current mechanical potentiometer solutions.

Available in small 5- and 6-pin SOT-23 and 2 mm x 3 mm DFN packages, the MCP4011 MCP4014 digital potentiometers help reduce board space and device height for handheld equipment and many portable consumer applications. The devices' ultra-low power consumption of 0.3 microamps (typical), along with their low, 1.8V operation increases battery life. Further, the low price point of the new devices enables use in applications that were previously cost-prohibitive.

"With the MCP4011, MCP4012, MCP4013, and MCP4014 digital potentiometers, Microchip continues to provide industry-leading, low-power analog products," said John Austin, senior product marketing engineer for Microchip's Analog and Interface Products Division. "These devices deliver the small package size and low power consumption that designers need for their applications, at a great value."

Additional features of the MCP4011 MCP4014 digital potentiometers include Integral Non-Linearity (INL) of 1/2 LSB (maximum), Differential Non-Linearity (DNL) of 1/2 LSB (maximum), end-to-end temperature coefficient of 100 ppm (typical), and ratiometric temperature coefficient of 10 ppm (typical). The new devices operate in the extended industrial temperature range of -40 degrees Celsius to +125 degrees Celsius.

The MCP4011 MCP4014 digital potentiometers provide a rich combination of features ideally suited for applications such as sensor calibration and trimming, set-point control, test and measurement, industrial process control, consumer electronics and data acquisition.

Development Support
To help engineers get started with the MCP4011-MCP4014 digital potentiometers, Microchip offers the low cost MCP402XEV Non-volatile Digital Potentiometer Evaluation Board (Part # MCP402XEV) for $15, available today. In addition, Microchip offers the FilterLab® 2.0 Active Filter Design Tool that simplifies active-filter design. Available today as a free download from Microchip's website, the FilterLab software gives users full schematic diagrams of the filter circuit with component values, and it displays the frequency response.

Pricing and Availability
The MCP4011, MCP4012, MCP4013, and MCP4014 are available for sampling today. Production orders are received today. The MCP4011 is offered in 8-pin, 2 mm x 3 mm DFN, MSOP and SOIC packages. The MCP4012 and MCP4013 are each available in a 6-pin SOT-23 package, and the MCP4014 is available in a 5-pin SOT-23 package. Pricing for all devices and package options is $0.36 each in 10,000-unit quantities.
