Learn how to use the AD5252 using our I2C Mini Module and take control of 2 on-board I2C controlled potentiometers, each with 256 taps. I ended up implementing all the functions that the chip provides, and I've packaged it up with some basic demos (I'll write some more demos of the various functions later, but I don't actually have the chip with me right now, so I can't test them until The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through R AW and R WB the string resistors, allowing very accurate resistor matching. This library only implements the I2C interface (See future for SPI). 73; 16,348 In Stock; Mfr. The AD5241/80 Instead of having to turn knobs with your HANDS like an ANIMAL, the DS3502 I2C Digital Potentiometer allows you to let your microcontroller adjust the resistance for you! Now you can free your hands to spin your fidget spinner or eat a slice of pizza while you're on the phone. 17; 7,052 In Stock; Using Arduino's I2C Wire Library, the digital pot will step through 64 levels of resistance, fading an LED. Mouser Part # 584 Data Sheet AD5251 /AD5252 Dual 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers Rev. The output of the wiper pin voltage will be measured by the Arduino’s A0 analog input pin. This example shows how to control a Analog Devices AD5171 Digital Potentiometer which communicates via the I2C synchronous serial protocol. This family offers 5kΩ, 10kΩ, 50kΩ or 100kΩ end-to-end resistance values and is available in miniature 5 or 6 lead SC-70 packaging with potentiometer or rheostat pinouts. The package it comes in is a SC70-6 which is even smaller than the ATtiny10 (side by side comparison above, ATtiny85 on the right too). It describes the device's resistor network, serial interface using I2C protocol, and typical configurations as a potentiometer or rheostat. 4 0.
