Working Principles

The MAX4460ETT+T is a voltage-feedback amplifier that uses a combination of transistors and resistors to amplify the input audio signal. It operates by applying a small input voltage to the non-inverting input (IN+) and amplifying it to a higher voltage at the output (OUT). The gain of the amplifier can be adjusted using external resistors connected to the IN+ and IN- pins.
