INA241A4QDDFRQ1 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 | Current-sense amplifier negative input; connect to the load side of the sense resistor for high-side use, or to the ground side for low-side use. |
| 2 | GND | power_in | Device ground. |
| 3 | REF2 | input | Reference 2 voltage, which must be between 0 V and VS; connect to a voltage potential (see the output-adjustment reference connection options). |
| 4 | NC | unconnected | Reserved pin; the datasheet says to connect it to ground. |
| 5 | OUT | output | Output voltage of the current-sense amplifier. |
| 6 | VS | power_in | Power supply, 2.7 V to 20 V. |
| 7 | REF1 | input | Reference 1 voltage, which must be between 0 V and VS; connect to a voltage potential (see the output-adjustment reference connection options). |
| 8 | IN+ | input | Current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side use, or to the load side for low-side use. |
