AD5273BRJZ1-REEL7 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 W; the voltage must stay within GND ≤ VW ≤ VDD. |
| 2 | VDD | power_in | Positive power supply specified for non-OTP operation from 2.7 V to 5.5 V; for OTP programming, VDD_OTP must be set within 5 V to 5.5 V for all end-to-end resistance options and be capable of sourcing 100 mA. |
| 3 | GND | power_in | Common ground for the device. |
| 4 | SCL | input | Serial clock input that requires a pull-up resistor; if driven directly from a logic controller without a pull-up, the VIH minimum must be 0.7 × VDD. |
| 5 | SDA | bidirectional | Serial data input/output that requires a pull-up resistor; if driven directly from a logic controller without a pull-up, the VIH minimum must be 0.7 × VDD. |
| 6 | AD0 | input | I2C device address bit that allows a maximum of two AD5273 devices to be addressed on the bus. |
| 7 | B | passive | Resistor terminal B; the voltage must stay within GND ≤ VB ≤ VDD. |
| 8 | A | passive | Resistor terminal A; the voltage must stay within GND ≤ VA ≤ VDD. |
