INA240A4DR from Texas Instruments, in a SOIC-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 | Analog input connected to load side of shunt resistor with common-mode voltage range of -4V to 80V. |
| 2 | GND | power_in | Analog ground reference. |
| 3 | REF2 | input | Reference 2 voltage input, connect to 0V to VS for output midpoint adjustment. |
| 4 | NC | unconnected | No internal connection; may be grounded or left floating. |
| 5 | OUT | output | Analog output voltage representing sensed current with output swing from GND to VS. |
| 6 | VS | power_in | Power supply input with operating voltage range of 2.7V to 5.5V. |
| 7 | REF1 | input | Reference 1 voltage input, connect to 0V to VS for output midpoint adjustment. |
| 8 | IN+ | input | Analog input connected to source side of shunt resistor with common-mode voltage range of -4V to 80V. |
