INA219AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | input | Address pin; determines I2C slave address (one of 16 possible addresses when connected to GND, VS, SDA, or SCL per Table 1). |
| 2 | A0 | input | Address pin; determines I2C slave address (one of 16 possible addresses when connected to GND, VS, SDA, or SCL per Table 1). |
| 3 | SDA | bidirectional | Serial bus data line with open-drain output for I2C/SMBus interface; supports fast mode (0.4 MHz) and high-speed mode (2.56 MHz). |
| 4 | SCL | input | Serial bus clock line for I2C/SMBus interface; supports fast mode (0.4 MHz) and high-speed mode (2.56 MHz). |
| 5 | VS | power_in | Analog power supply voltage, 3 to 5.5 V; bypass with 0.1 μF ceramic capacitor placed as close as possible to pin. |
| 6 | GND | power_in | Analog ground; connect to system ground plane. |
| 7 | IN- | input | Negative differential shunt voltage input (-0.3 to 26 V); connect to negative side of current-sense shunt resistor; bus voltage measured from this pin to ground. |
| 8 | IN+ | input | Positive differential shunt voltage input (-0.3 to 26 V); connect to positive side of current-sense shunt resistor; differential voltage range -26 to +26 V. |
