MCP4017/4018/4019 Digital PotentiometersMicrochips MCP4018 series are a range of great digital potentiometers. This range includes volatile memory all in a mini SC70 (SOT-323) package. The MCP4018's include options to have it in a potentiometer or rheostat configuration and feature a wide range of voltage options, from 1.8V up to 5.5V. These potentiometers are7-bit resolution (128 wiper steps). Digital potentiometers can be used in many applications that need a variable voltage resistance. Digital penetrometers are typically used where mechanical potentiometers are employed.Features and benefits: Rheostat or potentiometer configZero to full scale wiper operationLow power operation of only 2.5 μALow wiper resistance – typically 100 ΩExtended operating temperature: -40°C to +125°CWide operating voltageSimple I2C Protocol with read & write commandsNeed different resistance? 100KΩ – 738-6809Digital Potentiometer - Microchip
