# INA180A4IDBVR

**Texas Instruments** · Current-Sensing Amplifiers · SOT-23-5

INA180A4IDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Analog output voltage. Equals Gain × (V(IN+) − V(IN−)), where gain is 200 V/V for the A4 device. Referenced to GND; swing set by supply VS (2.7-5.5 V) and load conditions; slew rate 2 V/µs. |
| 2 | GND | power_in | Device ground reference for supply and analog output. Connect to system analog ground. |
| 3 | IN+ | input | Current-sense amplifier positive input. For high-side sensing, connect to the bus-voltage side of the sense resistor; for low-side sensing, connect to the load side of the sense resistor. Common-mode range −0.2 V to +26 V independent of VS. |
| 4 | IN- | input | Current-sense amplifier negative input. For high-side sensing, connect to the load side of the sense resistor; for low-side sensing, connect to the ground side of the sense resistor. Differential range ±26 V; common-mode range −0.2 V to +26 V. |
| 5 | VS | power_in | Positive power supply, 2.7 V to 5.5 V (absolute max 6 V). Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin. Quiescent current 260 µA max. |
