INA281A4IDBVR

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

INA281A4IDBVR 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 Output voltage representing the amplified differential voltage across the shunt resistor, with swing range of 0.005V to VS-0.07V.
2 GND power_in Ground reference, 0V potential.
3 IN+ input Positive differential input for shunt resistor voltage measurement, with common-mode range of -4V to +110V.
4 IN- input Negative differential input for shunt resistor voltage measurement, with common-mode range of -4V to +110V.
5 VS power_in Power supply voltage input with operating range of 2.7V to 20V.
