INA240A1EDRQ1 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 the load side of the shunt resistor; common-mode range is -4 V to 80 V independent of VS. |
| 2 | GND | power_in | Analog ground reference for the device. |
| 3 | REF2 | input | Reference 2 input connected to a voltage between 0 V and VS to set the output midpoint; must not be connected to any voltage below GND or above VS. |
| 4 | NC | unconnected | No internal connection; reserved, so connect to ground or leave floating. |
| 5 | OUT | output | Analog voltage output, referenced to the REF pins; output range is limited to GND - 0.3 V to VS + 0.3 V. |
| 6 | VS | power_in | Power supply input, 2.7 V to 5.5 V recommended operating range (6 V absolute maximum). |
| 7 | REF1 | input | Reference 1 input connected to a voltage between 0 V and VS to set the output midpoint; must not be connected to any voltage below GND or above VS. |
| 8 | IN+ | input | Analog input connected to the supply side of the shunt resistor; common-mode range is -4 V to 80 V independent of VS. |
