MCP4019T-103E

Microchip Tech · Digital Potentiometers · SC-70-5

MCP4019T-103E from Microchip Tech, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive power supply input, ranging from 1.8V to 5.5V relative to VSS; a decoupling capacitor to VSS is recommended.
2 VSS power_in Ground reference for the device.
3 SCL input I2C serial clock pin (Schmitt trigger, open drain); the device acts only as a slave and accepts only external serial clocks.
4 SDA bidirectional I2C serial data pin with Schmitt trigger input and open-drain output.
5 W passive Potentiometer wiper terminal, adjustable, supports positive and negative current, and its voltage must be between VSS and VDD.
