INA180A4IDBVT

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

INA180A4IDBVT 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 OUT output Analog output voltage of the current-sense amplifier, rated GND − 0.3 V to VS + 0.3 V, with a maximum output current of 8 mA and a specified swing of 30 mV max to the positive rail and 5 mV max to GND.
2 GND power_in Ground reference for the device; the common-mode input is rated GND − 0.3 V to 26 V.
3 IN+ input Positive current-sense amplifier input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing, with a common-mode range of −0.2 V to +26 V.
4 IN- input Negative current-sense amplifier input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing, with a common-mode range of −0.2 V to +26 V.
5 VS power_in Power supply input, 2.7 V to 5.5 V; a bypass capacitor of at least 0.1 µF should be placed close to the pin.
