Microchip Tech · Digital Potentiometers · MSOP-10

MCP4662-502E from Microchip Tech, in a MSOP-10. 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 HVC/A0 input High Voltage Command / Address 0 input; A0 address bit is latched at POR/BOR, and the voltage on the pin selects normal or High Voltage command (HVC/A0 = VIHH); high-voltage tolerant (up to 12.5V) with Schmitt trigger and smart pull-up.
2 SCL input I2C serial clock input from the host controller; the device is a slave so it accepts only external clock signals; high-voltage tolerant with Schmitt trigger.
3 SDA bidirectional I2C serial data I/O with an open-drain N-channel driver, connected to the host controller SDA; high-voltage tolerant with Schmitt trigger.
4 VSS power_in Device ground reference.
5 P1B passive Potentiometer 1 terminal B, the fixed zero-scale connection (wiper value 0x00); no polarity, voltage must be between VSS and VDD.
6 P1W passive Potentiometer 1 wiper terminal; no polarity, voltage must be between VSS and VDD.
7 P0W passive Potentiometer 0 wiper terminal; no polarity, voltage must be between VSS and VDD.
8 P0B passive Potentiometer 0 terminal B, the fixed zero-scale connection (wiper value 0x00); no polarity, voltage must be between VSS and VDD.
9 A1 input I2C Address 1 input which, with A2 and A0, allows up to eight devices on one I2C bus; high-voltage tolerant with Schmitt trigger and smart pull-up.
10 VDD power_in Positive power supply input relative to VSS; electrical performance may not meet specifications below 2.7V (device operation 1.8V to 5.5V).
