Digital Potentiometer

Microchip offers a wide variety of digital potentiometer (digipot) devices that service a broad range of applications, including but not limited to system calibration, gain and offset trimming, set-points, etc. These low-power, compact devices feature 6 to 8 bits of resolution, 1 to 4 channel counts, and are available in both volatile and non-volatile memory types. Tiny packages such as SC-70 and DFN (2x3) are offered for space constraint systems. High voltage digipot devices that can support +/- 18V dual voltage operation or 10V to 36V single voltage operation are also available.
