INA219AIDCNT from Texas Instruments, 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 | IN+ | input | Positive differential shunt voltage input; connect to positive side of shunt resistor; range ±40 mV to ±320 mV depending on PGA setting. |
| 2 | IN- | input | Negative differential shunt voltage input; connect to negative side of shunt resistor; bus voltage measured from this pin to ground. |
| 3 | GND | power_in | Analog ground. |
| 4 | VS | power_in | Analog power supply, 3 to 5.5 V. |
| 5 | SCL | input | Serial bus clock line for I²C/SMBus-compatible interface; digital input with open-drain structure. |
| 6 | SDA | bidirectional | Serial bus data line for I²C/SMBus-compatible interface; digital I/O with open-drain structure. |
| 7 | A0 | input | Address pin; logic level selects I²C slave address; sampled at start of each communication event. |
| 8 | A1 | input | Address pin; logic level selects I²C slave address; sampled at start of each communication event. |
