INA180B3QDBVRQ1

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

INA180B3QDBVRQ1 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 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.
2 GND power_in Analog ground.
3 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.
4 OUT output Analog output voltage.
5 VS power_in Analog power supply, 2.7 V to 5.5 V.
