    Products Detail

    The MCP40D17/18/19 series are single-channel 7-bit digital potentiometers (128 taps) featuring I2C protocol support. They offer resistance options of 5kΩ, 10kΩ, 50kΩ, or 100kΩ with low wiper resistance (typ. 100Ω). Devices operate from 1.8V to 5.5V with extended temperature range (-40°C to +125°C). Key features include brown-out reset protection, power-on default wiper setting (mid-scale), low-power operation (typ. 2.5µA static current), and very small SC70 packaging. Available in rheostat (MCP40D17/19) or potentiometer (MCP40D18) configurations.

    Key Features

    • I2C/SMBus 2.0 Protocol, 7-bit Resolution (128 Taps), Resistance Options: 5kΩ, 10kΩ, 50kΩ, 100kΩ, Low Wiper Resistance: 100Ω (typ), Low Tempco: 50ppm/°C (Rheostat), 15ppm/°C (Potentiometer), Wide Operating Voltage: 1.8V to 5.5V, Extended Temp Range: -40°C to +125°C, Low-Power: 2.5µA (typ), Brown-out Reset Protection, Power-on Default: Mid-scale, Very Small SC70 Package, Lead-Free
