Digital Potentiometer

Microchip’s large portfolio of Digital Potentiometers (DigiPots) service a broad range of precision-controlled applications. Our portfolio enables fine tuning with highly accurate, small form factor, digitally controlled resistor solutions. These low-power, compact devices feature six to eight bits of resolution, one- to four-channel counts and are available in both volatile and nonvolatile memory types to support a wide variety of design needs. Tiny packages such as SC-70 and DFN (2 x 3 mm) are offered for space-constrained systems.

Our digital potentiometers offer better precision because of our Integral Nonlinearity (INL), total unadjusted error specs and increase in resolution. Microchip’s digital potentiometers minimize development risk and increase system performance by providing reliable, well-documented functionality and quick fixes for design flaws.
