Working Principles

The MAX9723DETE+C5D is a stereo audio amplifier that operates by amplifying the input audio signals received at the INL+ and INR+ pins. The amplified signals are then output through the OUTL and OUTR pins, respectively. The amplifier can be powered by a supply voltage ranging from 2.7V to 5.5V.

The BYP pin allows for the connection of an external bypass capacitor, which helps reduce noise and improve overall audio quality. The SHDN pin enables the amplifier to enter a low-power shutdown mode when not in use, minimizing power consumption.
