Each of the four channels is independently adjustable via the I²C interface; the selectable address feature (three address pins) allows up to eight devices on the same bus, giving 32 total potentiometer channels in a compact footprint. ## Industrial temperature range and sourcing posture Sourced to order against an RFQ; pricing and lead time confirmed at quote time. ## Wiper resistance and tolerance — design margin note The wiper resistance is 75 Ω typical, which sets a floor on the minimum output impedance when the wiper is near the low end of the resistor string.","metaTitle":"MCP4451-104E/ST Digital Potentiometer, 100k, I²C, 20-TSSOP","metaDescription":"Microchip MCP4451-104E/ST digital pot: 100k resistance, 4 circuits, 257 taps, I²C interface, -40 to 125°C.
