INA210BIRSWR from Texas Instruments, in a UQFN-10(1.4x1.8). 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 | NC | unconnected | No internal connection; the pin may be left floating or tied to GND. |
| 2 | IN+ | input | Analog input connected to the supply side of the shunt resistor; both IN+ pins (2 and 3) must be connected together. |
| 3 | IN+ | input | Analog input connected to the supply side of the shunt resistor; both IN+ pins (2 and 3) must be connected together. |
| 4 | IN- | input | Analog input connected to the load side of the shunt resistor; both IN- pins (4 and 5) must be connected together. |
| 5 | IN- | input | Analog input connected to the load side of the shunt resistor; both IN- pins (4 and 5) must be connected together. |
| 6 | V+ | power_in | Analog power supply input, 2.7 V to 26 V. |
| 7 | NC | unconnected | No internal connection; the pin may be left floating or tied to GND. |
| 8 | REF | input | Reference voltage input, 0 V to V+, that sets the output level for zero differential input; it must be buffered by an op amp when driven from a resistive divider. |
| 9 | GND | power_in | Analog ground reference for the device. |
| 10 | OUT | output | Analog voltage output; with RL = 10 kΩ to GND it swings to (V+) − 0.05 V to (V+) − 0.2 V at the top and (GND) + 0.005 V to (GND) + 0.05 V at the bottom. |
