Texas Instruments · Current Sense Amplifiers · UQFN-10(1.4x1.8)
INA190A1IRSWR 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 | Not internally connected; float or connect to any voltage between GND and VS. |
| 2 | NC | unconnected | Not internally connected; float or connect to any voltage between GND and VS. |
| 3 | IN+ | input | Positive current-sense amplifier input; connect to bus voltage side of sense resistor (high-side) or load side (low-side). |
| 4 | IN- | input | Negative current-sense amplifier input; connect to load side of sense resistor (high-side) or ground side (low-side). |
| 5 | NC | unconnected | Not internally connected; float or connect to any voltage between GND and VS. |
| 6 | VS | power_in | Analog power supply voltage, operating range 1.7 V to 5.5 V. |
| 7 | ENABLE | input | Enable input; driven to VS enables device operation, driven to GND disables operation with output in high-impedance state; must be driven externally or connected to VS if not used. |
| 8 | REF | input | Reference input enabling bidirectional current sensing with externally applied voltage offset. |
| 9 | GND | power_in | Analog ground. |
| 10 | OUT | output | Analog output voltage providing the gained voltage difference between IN+ and IN- pins, offset by the voltage applied to the REF pin. |
