INA190A5IDDFR from Texas Instruments, in a TSOT-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 | VS | power_in | Power supply, 1.7 V to 5.5 V. |
| 2 | ENABLE | input | Enable pin: driven to VS the device is on as a current sense amplifier; driven to GND the device is off, supply current is reduced and the output is high-impedance; must be driven externally or connected to VS if not used. |
| 3 | REF | input | Reference input that enables bidirectional current sensing with an externally applied voltage. |
| 4 | GND | power_in | Analog ground. |
| 5 | OUT | output | Analog voltage output that is the gained up voltage difference from IN+ to IN-, offset by the voltage applied to the REF pin. |
| 6 | NC | unconnected | Not internally connected; either float this pin or connect to any voltage between GND and VS. |
| 7 | 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 of sense resistor. |
| 8 | 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 of sense resistor. |
