**Analog Devices** · Digital Potentiometers · SC-70-6

AD5246BKSZ5-RL7 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, with absolute maximum VDD to GND of −0.3 V to +7 V. |
| 2 | GND | power_in | Digital ground, which should be joined remotely to the analog ground at one point to minimize ground bounce. |
| 3 | SCL | input | Serial clock input, positive edge triggered, with VIH of 2.4 V minimum and VIL of 0.8 V maximum at VDD = 5 V. |
| 4 | SDA | bidirectional | Serial data input/output for the I2C interface, with VIH of 2.4 V minimum and VIL of 0.8 V maximum at VDD = 5 V. |
| 5 | W | passive | Wiper terminal of the RDAC, which may be at any voltage between GND and VDD, with continuous terminal current limited to ±5 mA and pulsed current to ±20 mA. |
| 6 | B | passive | B terminal of the RDAC, which may be at any voltage between GND and VDD, with continuous terminal current limited to ±5 mA and pulsed current to ±20 mA. |
