INA181A2IDBVT

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

INA181A2IDBVT 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 of the current sense amplifier, limited to the range GND - 0.3 V to VS + 0.3 V with a maximum output current of 8 mA.
2 GND power_in Ground.
3 IN+ input Positive input of the current sense amplifier; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing, with common-mode range -0.2 V to +26 V.
4 IN- input Negative input of the current sense amplifier; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing, with common-mode range -0.2 V to +26 V.
5 REF input Reference voltage input that sets the output level at zero differential input, settable from 0 V to VS.
6 VS power_in Power supply, 2.7 V to 5.5 V.
