Working Principles

The MAX9700CETB+T is a stereo Class D audio amplifier that utilizes pulse-width modulation (PWM) to amplify audio signals. It operates by rapidly switching the input signal on and off, using a high-frequency carrier wave. This allows for efficient power conversion and minimizes heat dissipation.

The amplifier's internal circuitry includes a feedback loop that continuously monitors the output signal and adjusts the PWM modulation to maintain accurate amplification. The result is high-quality audio reproduction with low distortion and high efficiency.

Detailed Application Field Plans

The MAX9700CETB+T is suitable for a wide range of audio amplification applications, including:

1. Portable audio devices such as smartphones, tablets, and MP3 players
2. Home audio systems and multimedia speakers
3. Automotive audio systems
4. Gaming consoles and entertainment systems
5. Professional audio equipment
