DFRobot MCP42100 Dual Digital SPI Potentiometer Module 100kOhm

The MCP42100 dual digital SPI potentiometer module is a highly flexible and reliable tool for your projects. It is a mixed-signal IC that can dynamically change the internal resistances via a microcontroller like Arduino. Compared to traditional mechanical potentiometers, this digital potentiometer offers advantages such as programmable control, small size, and high reliability. It is ideal for applications such as LED DC dimming, linear stable voltage sources, oscillators, low-pass filters, and differential amplifiers.

Note: The resistance terminals A, B, and W have no polarity restrictions relative to each other. The current through terminals A, B, and W should not exceed ±1mA. The voltages at terminals A, B, and W should be in the range of 0 - VCC.
