INA219BIDCNT 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, differential voltage range -26 to +26 V maximum. |
| 2 | IN- | input | Negative differential shunt voltage input, common-mode voltage range -0.3 to 26 V maximum. |
| 3 | GND | power_in | Analog ground reference connection. |
| 4 | VS | power_in | Analog power supply voltage, operating range 3 to 5.5 V, absolute maximum 6 V. |
| 5 | SCL | input | Serial bus clock line for I²C/SMBus interface, voltage range GND-0.3 to VS+0.3 V maximum. |
| 6 | SDA | bidirectional | Serial bus data line for I²C/SMBus interface (open-drain output), voltage range GND-0.3 to 6 V maximum. |
| 7 | A0 | input | Address selection input pin for I²C slave address configuration, state sampled on every bus communication. |
| 8 | A1 | input | Address selection input pin for I²C slave address configuration, state sampled on every bus communication. |
