INA190A4IDDFR 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 | Analog power supply, 1.7 V to 5.5 V |
| 2 | ENABLE | input | Digital input enable pin; device operates when driven to VS and is disabled with reduced supply current when driven to GND. |
| 3 | REF | input | Reference input for bidirectional current sensing with externally applied voltage. |
| 4 | GND | power_in | Analog ground |
| 5 | OUT | output | Analog output voltage proportional to IN+ to IN- difference, offset by REF voltage. |
| 6 | NC | unconnected | Not internally connected; float or connect between GND and VS. |
| 7 | IN+ | input | Current-sense amplifier positive input to measure voltage across sense resistor. |
| 8 | IN- | input | Current-sense amplifier negative input to measure voltage across sense resistor. |
