{"title":"Adafruit DS1841 I2C Digital 10K Potentiometer Breakout","handle":"adafruit-ds1841-i2c-digital-10k-potentiometer-breakout","url":"/products/adafruit-ds1841-i2c-digital-10k-potentiometer-breakout","description":"The Adafruit DS1841 is an I2C-controlled logarithmic digital potentiometer from Maxim with a resistance range of 3.7 kΩ to 22 kΩ across 128 tap points. Unlike linear potentiometers, the DS1841's logarithmic response curve makes it particularly well suited for audio applications such as volume control, where it better matches the human ear's perception of sound levels.\n\nThe DS1841 also features built-in temperature compensation with hysteresis, plus a 72-entry look-up table (LUT) that maps specific wiper positions to temperature ranges from -39°C to 100°C. The breakout includes STEMMA QT / Qwiic connectors for solderless I2C wiring and works with 3.3V or 5V logic.\n\nKey Features\n\n\nLogarithmic Response – Ideal for audio volume control and human-perception-matched applications\n\n128 Tap Points – Fine resolution across 3.7 kΩ to 22 kΩ range\n\nTemperature Compensation – Built-in automatic resistance adjustment based on temperature\n\n72-Entry Look-Up Table – Map wiper positions to specific temperature ranges\n\nI2C Control – Simple digital interface with STEMMA QT / Qwiic connectors\n\n3.3V and 5V Compatible – Works with a wide range of microcontrollers\n\n\nIdeal For\n\nAudio volume control circuits\nTemperature-compensated analogue adjustments\nDigitally controlled calibration\nReplacing mechanical potentiometers with software control\n\n\nPackage Contents\n\n1× DS1841 I2C logarithmic potentiometer breakout with STEMMA QT connectors\n\n\n\nNote: STEMMA QT cable not included. Compatible with CircuitPython and Arduino libraries.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2979,"title":"Default Title","sku":"AF-4570","price":12.08,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":28,"option1":"Default Title"}]}
