# INA180B2IDBVT

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

INA180B2IDBVT from Texas Instruments, in a SOT-23-5. 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 | IN+ | input | Positive current-sense amplifier input; in high-side use connect to the bus-voltage side of the sense resistor, and in low-side use connect to the load side. The common-mode input range is -0.2 V to +26 V. |
| 2 | GND | power_in | Analog ground reference for the device. |
| 3 | IN- | input | Negative current-sense amplifier input; in high-side use connect to the load side of the sense resistor, and in low-side use connect to the ground side of the sense resistor. The common-mode input range is -0.2 V to +26 V. |
| 4 | OUT | output | Analog output voltage of the current-sense amplifier; the output swing is limited by the supply VS and GND, and the capacitive load should not exceed 1 nF for stable operation. |
| 5 | VS | power_in | Power supply pin, operating range 2.7 V to 5.5 V, to be bypassed with at least 0.1 µF close to the device. |
