INA241A3IDDFR from Texas Instruments, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN- | input | Current-sense amplifier negative input; for high-side applications connect to load side of sense resistor, for low-side applications connect to ground side. |
| 2 | GND | power_in | Ground |
| 3 | REF2 | input | Reference 2 voltage input; connect to voltage potential from 0 V to VS. |
| 4 | NC | unconnected | Reserved pin; connect to ground. |
| 5 | OUT | output | Output voltage; minimum swing to ground 20 mV, maximum swing to VS − 0.2 V. |
| 6 | VS | power_in | Power supply input; 2.7 V to 20 V. |
| 7 | REF1 | input | Reference 1 voltage input; connect to voltage potential from 0 V to VS. |
| 8 | IN+ | input | Current-sense amplifier positive input; for high-side applications connect to bus-voltage side of sense resistor, for low-side applications connect to load side. |
