INA181A3QDBVRQ1

Texas Instruments · Current Sense Amplifiers · SOT-23-6

INA181A3QDBVRQ1 from Texas Instruments, in a SOT-23-6. 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
2 GND power_in Analog ground
3 IN+ input Current sense amplifier positive input; for high-side applications connect to bus voltage side of sense resistor; for low-side applications connect to load side of sense resistor
4 IN- input Current sense amplifier negative input; for high-side applications connect to load side of sense resistor; for low-side applications connect to ground side of sense resistor
5 REF input Reference input voltage, 0 to VS
6 VS power_in Analog power supply, 2.7V to 5.5V
