MCP4531-503E

Microchip Tech · Digital Potentiometers · MSOP-8

MCP4531-503E from Microchip Tech, in a MSOP-8. 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, whose value is latched at POR/BOR for the I2C address, and when driven at VIHH it selects High Voltage command mode.
2 SCL input I2C serial clock input that accepts only external clock signals from the host, as a high-voltage tolerant input with Schmitt trigger.
3 SDA bidirectional I2C serial data I/O implemented as an open-drain N-channel driver, as a high-voltage tolerant input with Schmitt trigger.
4 VSS power_in Device ground reference.
5 P0A passive Potentiometer 0 terminal A, the fixed connection to the full-scale wiper value (0x80 for 7-bit devices), with voltage that must be between VSS and VDD.
6 P0W passive Potentiometer 0 wiper terminal, which may carry positive or negative current, with voltage that must be between VSS and VDD.
7 P0B passive Potentiometer 0 terminal B, the fixed connection to the zero-scale wiper value (0x00), with voltage that must be between VSS and VDD.
8 VDD power_in Positive power supply input relative to VSS; electrical performance may not meet the data sheet specifications while VDD is below 2.7V.
