Working Principles

LMV771MG is based on a differential amplifier configuration that amplifies the voltage difference between its two input terminals. It utilizes a combination of transistors and resistors to achieve the desired amplification characteristics. The IC operates by applying the input signal to the non-inverting input terminal (IN+) and providing feedback through the inverting input terminal (IN-). The amplified output signal is then available at the OUT pin.
