AD5245BRJZ10-RL7 from Analog Devices, in a SOT-23-8. 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 W passive Wiper terminal; the datasheet specifies GND ≤ VW ≤ VDD.
2 VDD power_in Positive power supply; the part operates from 2.7 V to 5.5 V.
3 GND power_in Digital ground.
4 SCL input I2C serial clock input, positive-edge triggered; an external pull-up resistor is required.
5 SDA bidirectional I2C serial data input/output; an external pull-up resistor is required.
6 AD0 input Programmable address bit 0 used to decode two devices on the same I2C bus.
7 B passive B terminal of the variable resistor; the datasheet specifies GND ≤ VB ≤ VDD.
8 A passive A terminal of the variable resistor; the datasheet specifies GND ≤ VA ≤ VDD.
