INA210CQDCKRQ1 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, which must be set between 0 V and V+ to define the output level at zero differential input. |
| 2 | GND | power_in | Ground connection for the device. |
| 3 | V+ | power_in | Power supply input, specified from 2.7 V to 26 V. |
| 4 | IN+ | input | Connects to the power-supply side of the shunt resistor. |
| 5 | IN- | input | Connects to the load side of the shunt resistor. |
| 6 | OUT | output | Voltage output that carries the amplified shunt voltage, referenced to REF and limited by the V+ supply rail. |
