INA199C3RSWR 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; may be left floating or connected to any voltage between GND and V+. |
| 2 | IN+ | input | Analog input; connect to power supply side of shunt resistor; must be tied together with pin 3. |
| 3 | IN+ | input | Analog input; connect to power supply side of shunt resistor; must be tied together with pin 2. |
| 4 | IN- | input | Analog input; connect to load side of shunt resistor; must be tied together with pin 5. |
| 5 | IN- | input | Analog input; connect to load side of shunt resistor; must be tied together with pin 4. |
| 6 | V+ | power_in | Analog power supply, 2.7V to 26V. |
| 7 | NC | unconnected | No internal connection; may be left floating or connected to any voltage between GND and V+. |
| 8 | REF | input | Analog reference input voltage, 0V to V+; sets output offset for single-ended or bidirectional operation. |
| 9 | GND | power_in | Analog ground; return path for signal and power circuits. |
| 10 | OUT | output | Analog output; 200V/V gain with output swing from GND+5mV to V+-50mV into 10kΩ load. |
