MCP4462-103E from Microchip Tech, in a TSSOP-14. 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	P3W	passive	Potentiometer 3 wiper terminal, analog pin whose voltage must be between VSS and VDD.
2	P3B	passive	Potentiometer 3 terminal B (zero-scale end, wiper value 0x00), analog pin with no polarity whose voltage must be between VSS and VDD.
3	HVC/A0	input	High Voltage Command / I2C Address 0 input; A0 is latched at POR/BOR and a voltage of VIHH selects a high-voltage command.
4	SCL	input	I2C serial clock input (high-voltage tolerant with Schmitt trigger), connected to the host controller SCL; the device is a slave.
5	SDA	bidirectional	I2C serial data I/O (high-voltage tolerant with Schmitt trigger) with an open-drain N-channel output.
6	VSS	power_in	Ground reference for the device.
7	P1B	passive	Potentiometer 1 terminal B (zero-scale end), analog pin whose voltage must be between VSS and VDD.
8	P1W	passive	Potentiometer 1 wiper terminal, analog pin whose voltage must be between VSS and VDD.
9	P0W	passive	Potentiometer 0 wiper terminal, analog pin whose voltage must be between VSS and VDD.
10	P0B	passive	Potentiometer 0 terminal B (zero-scale end), analog pin whose voltage must be between VSS and VDD.
11	A1	input	I2C Address 1 input (high-voltage tolerant with Schmitt trigger and smart pull-up); with A0 allows up to 4 devices on one I2C bus.
12	VDD	power_in	Positive power supply input relative to VSS; specifications are guaranteed for 2.7V to 5.5V, with operation from 1.8V.
13	P2B	passive	Potentiometer 2 terminal B (zero-scale end), analog pin whose voltage must be between VSS and VDD.
14	P2W	passive	Potentiometer 2 wiper terminal, analog pin whose voltage must be between VSS and VDD.
