There are times when you want to tune your circuit without manually turning a knob, and Maxim's DS1841 I2C Logarithmic Resistor can do just that. It is a programmable resistor, similar to an I2C potentiometer like the DS3502 I2C potentiometer, so why another one? The big difference between the two is how the resistance changes in relation to changes to the wiper. The resistance of the DS3502 has a linear relationship to the windshield wiper adjustment. Every time you change the wipers a certain amount, the resistance changes by the same amount. With the DS1841, the relationship between resistance and wiper setting is logarithmic. This means that when you change the wiper setting, the wiper setting of the resistors depends on where the current setting is in the area of the wiper blade. Protocol potentiometers are used in audio applications for things like volume controls because they better match the human ear's response to sound. The DS1841's resistance ranges from 22kOhm to 3.7kOhm and has 128 tap points. Even more interestingly, the DS1841 can be configured to adjust its resistance based on temperature with hysteresis to prevent things from jumping around. Dimensions: 25.5mm x 17.6mm x 4.6mm.\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003eThis is a brilliant little programmable resistor, similar an I2C potentiometer.\u003c\/li\u003e \u003cli\u003eThe resistance ranges from 22 kOhm to 3.7 kOhm and has 128 tap points.\u003c\/li\u003e \u003cli\u003eCan be quickly and easily configured to adjust its resistance to the temperature with hysteresis to prevent things from jumping around.\u003c\/li\u003e \u003cli\u003eThis handy little helper can work with 3.3V or 5V micros, making it ready to work with a range of development boards.\u003c\/li\u003e \u003cli\u003eHigh quality product.\u003c\/li\u003e\n\u003c\/ul\u003e","published_at":"2024-03-09T05:07:28+11:00","created_at":"2024-03-09T05:07:32+11:00","vendor":"Adafruit","type":"Potentiometers","tags":["industryDE"],"price":14500,"price_min":14500,"price_max":14500,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":48994844213408,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"de-B08GYP8L24","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit DS1841 I2C Digital Potentiometer Breakout, STEMMA QT\/Qwiic","public_title":null,"options":["Default Title"],"price":14500,"weight":10,"compare_at_price":null,"inventory_management":"shopify","barcode":"3738","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/dingoship.com.au\/cdn\/shop\/files\/de-B08GYP8L24.jpg?v=1709942671","\/\/dingoship.com.au\/cdn\/shop\/products\/81Hh6MTVP-L.jpg?v=1709921252"],"featured_image":"\/\/dingoship.com.au\/cdn\/shop\/files\/de-B08GYP8L24.jpg?v=1709942671","options":["Title"],"media":[{"alt":null,"id":32719433203872,"position":1,"preview_image":{"aspect_ratio":1.333,"height":900,"width":1200,"src":"\/\/dingoship.com.au\/cdn\/shop\/files\/de-B08GYP8L24.jpg?v=1709942671"},"aspect_ratio":1.333,"height":900,"media_type":"image","src":"\/\/dingoship.com.au\/cdn\/shop\/files\/de-B08GYP8L24.jpg?v=1709942671","width":1200},{"alt":null,"id":32715872796832,"position":2,"preview_image":{"aspect_ratio":1.333,"height":900,"width":1200,"src":"\/\/dingoship.com.au\/cdn\/shop\/products\/81Hh6MTVP-L.jpg?v=1709921252"},"aspect_ratio":1.333,"height":900,"media_type":"image","src":"\/\/dingoship.com.au\/cdn\/shop\/products\/81Hh6MTVP-L.jpg?v=1709921252","width":1200}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit DS1841 I2C Digital Potentiometer Breakout, STEMMA QT\/Qwiic\u003c\/h3\u003e \u003cp id=\"b\"\u003ePotentiometers are the perfect tool if you want to change your circuit by turning a knob.
