INA240A3PWR from Texas Instruments, in a TSSOP-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 | NC | unconnected | Reserved pin; ground or leave floating. |
| 2 | IN+ | input | Analog input, connect to the positive side of the shunt resistor; operates from -4V to +80V common mode. |
| 3 | IN- | input | Analog input, connect to the negative side of the shunt resistor; operates from -4V to +80V common mode. |
| 4 | GND | power_in | Analog ground reference. |
| 5 | VS | power_in | Positive power supply; nominal 2.7V to 5.5V. |
| 6 | REF2 | input | Analog input for reference voltage 2; adjusts output midpoint; connect 0V to VS. |
| 7 | REF1 | input | Analog input for reference voltage 1; adjusts output midpoint; connect 0V to VS. |
| 8 | OUT | output | Analog output voltage; output swing limited by supply voltage VS. |
