Working Principles

The INA195AIDBVTG4 is a current sense amplifier that utilizes a precision resistor in series with the load to measure the current. The voltage drop across this resistor is amplified by the internal operational amplifier, providing an output voltage proportional to the sensed current. The device operates in a differential mode, where the voltage difference between the Vin+ and Vin- inputs is amplified.
