MCP4023T-103E

Microchip Tech · Digital Potentiometers · SOT-23-6

MCP4023T-103E from Microchip Tech, in a SOT-23-6. 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, relative to VSS, 2.7V to 5.5V, with a decoupling capacitor to VSS recommended.
2 VSS power_in Device ground reference.
3 U/D input TTL-compatible Increment/Decrement input; an increment moves the wiper one step toward terminal A and a decrement one step toward terminal B.
4 CS input TTL-compatible chip select input with internal pull-up; VIL enables serial commands and VIHH enables high-voltage serial commands (wiper save and WiperLock control).
5 W passive Potentiometer wiper terminal, the adjustable terminal; supports positive and negative current and must be between VSS and VDD.
6 A passive Potentiometer terminal A, fixed connection to the 0x3F end; no polarity, supports positive and negative current, must be between VSS and VDD.
