MCP4532T-104E 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 tolerant (up to 12.5V) Schmitt-trigger input serving as I2C Address 0 (latched at POR/BOR) and as the High Voltage command pin when driven to VIHH. |
| 2 | SCL | input | I2C serial clock input from the host; the device is a slave and accepts only external clock signals (high-voltage tolerant, Schmitt trigger). |
| 3 | SDA | bidirectional | I2C serial data I/O with an open-drain N-channel output driver (high-voltage tolerant, Schmitt trigger). |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | P0W | passive | Potentiometer 0 wiper terminal (rheostat wiper); supports positive and negative current and its voltage must be between VSS and VDD. |
| 6 | P0B | passive | Potentiometer 0 terminal B, the fixed zero-scale connection (wiper value 0x00); supports positive and negative current and its voltage must be between VSS and VDD. |
| 7 | A1 | input | I2C Address 1 input (high-voltage tolerant, Schmitt trigger) which, with A2 and A0, allows up to eight devices on one I2C bus. |
| 8 | VDD | power_in | Positive power supply input relative to VSS; device operation 1.8V to 5.5V, characteristics specified 2.7V to 5.5V. |
