INA190A3QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 | REF | input | Reference voltage input for bidirectional current sensing, accepts 0V to VS. |
| 2 | GND | power_in | Analog ground connection. |
| 3 | VS | power_in | Analog power supply pin, rated for 1.7V to 5.5V. |
| 4 | IN+ | input | Positive input of current-sense amplifier, accepts common-mode voltage −0.2V to +40V. |
| 5 | IN- | input | Negative input of current-sense amplifier, accepts common-mode voltage −0.2V to +40V. |
| 6 | OUT | output | Output voltage equal to (IN+ − IN−) × Gain + VREF, output swing 0.05mV to VS−40mV. |
