Texas Instruments · Current Sense Amplifiers · UQFN-10(1.4x1.8)
INA190A3IRSWR 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 this pin or connect it to any voltage between GND and VS. |
| 2 | NC | unconnected | Not internally connected; float this pin or connect it to any voltage between GND and VS. |
| 3 | IN+ | input | Current-sense amplifier positive input; connect to the bus voltage side of the sense resistor for high-side applications, or to the load side for low-side applications. |
| 4 | IN- | input | Current-sense amplifier negative input; connect to the load side of the sense resistor for high-side applications, or to the ground side for low-side applications. |
| 5 | NC | unconnected | Not internally connected; float this pin or connect it to any voltage between GND and VS. |
| 6 | VS | power_in | Analog power supply, specified from 1.7 V to 5.5 V. |
| 7 | ENABLE | input | Enable pin; driving it to VS turns the device on as a current sense amplifier, while driving it to GND turns it off, reduces supply current and places OUT in a high-impedance state, and it must be driven externally or connected to VS if not used. |
| 8 | REF | input | Reference input that enables bidirectional current sensing with an externally applied voltage, with a recommended range of GND to VS. |
| 9 | GND | power_in | Analog ground. |
| 10 | OUT | output | Analog voltage output equal to the gained-up voltage difference from IN+ to IN-, offset by the voltage applied to REF. |
