Working Principles

The LMV722M/NOPB is an operational amplifier designed to amplify and condition electrical signals. It operates on a low supply voltage, making it suitable for use in battery-powered devices. The rail-to-rail input and output capability ensures that the amplifier can handle signals close to the power supply rails, maximizing the dynamic range.

The amplifier amplifies the difference between the non-inverting (IN+) and inverting (IN-) inputs, and produces an amplified output signal at the OUT pin. The gain and behavior of the amplifier can be adjusted using external resistors and capacitors connected to the appropriate pins.
