MCP4532-503E 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-tolerant (up to 12.5V) Schmitt-trigger input that latches the I2C Address 0 bit at POR/BOR and, when at VIHH, marks an I2C command as a High Voltage command.
2	SCL	input	I2C serial clock input from the host controller; the device is a slave and accepts only external clock signals.
3	SDA	bidirectional	I2C serial data I/O with an open-drain N-channel output driver, connected to the host controller's SDA.
4	VSS	power_in	Device ground reference.
5	P0W	passive	Potentiometer 0 wiper terminal, the adjustable terminal; it carries positive or negative current and its voltage must be between VSS and VDD.
6	P0B	passive	Potentiometer 0 terminal B, the fixed connection to the zero-scale wiper value (0x00); it carries positive or negative current and its voltage must be between VSS and VDD.
7	A1	input	High-voltage-tolerant Schmitt-trigger I2C Address 1 input that, with A2 and A0, allows up to eight devices on one I2C bus.
8	VDD	power_in	Positive power supply input relative to VSS; the device operates from 1.8V to 5.5V, with characteristics specified from 2.7V to 5.5V.
