Working Principles

The MAX97220EETE+T is a stereo audio amplifier that operates by amplifying the input audio signals received on the INL+/INL- and INR+/INR- pins. The amplified audio signals are then delivered to the respective left and right channel outputs (OUTL and OUTR). The amplifier is powered by the VDD and PVDD supply voltages, which can range from 2.7V to 5.5V.

The amplifier incorporates various protection mechanisms such as short-circuit and thermal protection to prevent damage to the device and connected speakers. Additionally, the shutdown input (SHDN) allows for power-saving functionality by disabling the amplifier when not in use.

Detailed Application Field Plans

The MAX97220EETE+T is suitable for a wide range of audio amplification applications, including but not limited to:

1. Portable audio devices: MP3 players, smartphones, tablets
2. Headphone amplifiers
3. Multimedia systems: laptops, desktop computers, gaming consoles
4. Home audio systems: mini hi-fi systems, soundbars
5. Automotive audio systems: car stereos, amplifiers
