# INA214CIRSWR

**Texas Instruments** · Current Sense Amplifiers · UQFN-10(1.4x1.8)

INA214CIRSWR 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; can be left floating or connected to any voltage between V- and V+. |
| 2 | IN+ | input | Positive input to shunt sense amplifier; connect to shunt resistor power-side terminal. |
| 3 | IN+ | input | Positive input to shunt sense amplifier; connect in parallel with pin 2. |
| 4 | IN- | input | Negative input to shunt sense amplifier; connect to shunt resistor load-side terminal. |
| 5 | IN- | input | Negative input to shunt sense amplifier; connect in parallel with pin 4. |
| 6 | V+ | power_in | Analog power supply, 2.7V to 26V. |
| 7 | NC | unconnected | No internal connection; can be left floating or connected to any voltage between V- and V+. |
| 8 | REF | input | Reference voltage input (0V to V+) that establishes the zero-current output baseline voltage. |
| 9 | GND | power_in | Analog ground reference. |
| 10 | OUT | output | Analog voltage output proportional to shunt current with 100 V/V gain; output swing (V+)−0.05 V to (V+)−0.2 V and (GND)+0.005 V to (GND)+0.05 V. |
