Working Principles

The MAX9718DEUB+ is a Class D audio amplifier that utilizes pulse-width modulation (PWM) to amplify the audio signal. It operates by rapidly switching the output stage between two states, allowing for efficient power conversion and minimizing power dissipation. The audio input signal is converted into a high-frequency PWM signal, which is then amplified and filtered to produce the final audio output.

Detailed Application Field Plans

The MAX9718DEUB+ is suitable for various audio amplification applications, including: - Portable audio devices such as smartphones, tablets, and MP3 players - Headphone amplifiers - Multimedia speakers - Automotive audio systems - Home theater systems

Alternative Models

• MAX9717DEUB+: Similar specifications and features, but with a different package (µMAX®)
• MAX9719DEUB+: Higher output power capability (up to 2.4W per channel), otherwise similar to MAX9718DEUB+
