Adafruit DS1841 Digital Potentiometer Breakout

Adafruit DS1841 Digital Potentiometer Breakout is a programmable I2C logarithmic resistor from Maxim that offers a logarithmic relationship between resistance and the wiper setting. This potentiometer features 128 tap points and resistance values range from 3.7kΩ to 22kΩ. The DS1841 can be configured to adjust the resistance based on temperature and the temperature compensation is adjusted by using the built-in LUT (Look Up Table). This potentiometer is available on a breakout PCB with required support circuitry and SparkFun Qwiic compatible STEMMA QT connectors for solderless connection. The DS1841 potentiometer is used in audio applications for volume control.
