Chandler, Ariz. Microchip Technology Inc. announced a family of low-power, low-voltage, 6-bit digital potentiometers that are said to be cost and size competitive with mechanical versions.
Available in 5- and 6-pin SOT-23 and 2 x 3-mm DFN packages, the MCP4011 – MCP4014 digital potentiometers can be used in handheld equipment and portable applications including sensor calibration and trimming, set-point control, test and measurement, industrial process control, consumer electronics and data acquisition.
The pots feature power consumption of 0.3 microamps (typical) and 1.8-volt operation. Additional features of the digital potentiometers include integral non-linearity (INL) of 1/2 least significant bit (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 devices operate in the extended industrial temperature range of -40°C to +125°C.
An evaluation board (MCP402XEV) is available for $15.00. In addition, Microchip offers the FilterLab 2.0 active filter design tool that simplifies active-filter design.
The MCP4011, MCP4012, MCP4013, and MCP4014 are available now. The MCP4011 is offered in 8-pin, 2 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 36 cents each in 10,000-unit quantities. Click here for the MCP401X data sheets.
