AD5247BKSZ10-2RL7 from Analog Devices, in a SC-70-6. 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 | VDD | power_in | Positive power supply, specified from 2.7 V to 5.5 V (Power Supply Range). |
| 2 | GND | power_in | Digital ground and B terminal voltage; the B terminal is tied to this pin. |
| 3 | SCL | input | I2C serial clock input, positive-edge triggered. |
| 4 | SDA | bidirectional | I2C serial data input/output; output logic low is 0.4 V max at IOL = 3 mA (5 V) and 0.6 V max at IOL = 6 mA. |
| 5 | W | passive | Resistor Terminal W (wiper); voltage must stay between GND and VDD, with no polarity limitation relative to Terminal A. |
| 6 | A | passive | Resistor Terminal A; voltage must stay between GND and VDD, with no polarity limitation relative to Terminal W. |
