Working Principle

The MAX9717CEBL+T is a linear audio power amplifier with integrated power switching. It uses a unique combination of techniques to achieve high efficiency while maintaining high performance and good sound quality. The device operates in two distinct modes. In Class G mode, it uses a combination of pulse width modulation and fully linear output to provide high efficiency. In Class AB mode, the output is fully linear, switching in and out a high power, low loss, Class-G amplifier to ensure high performance with good power efficiency.

The device uses a unique method of power management which ensures that the right amount of power is available for the operation of the amplifier at any given time. It also uses an adjustable gain profile, as well as a low-impedance output stage, to optimize sound quality and reduce distortion. The MAX9717CEBL+T also offers a variety of integrated protection features, such as short-circuit, open-circuit and thermal protection, to ensure proper and safe operation of the amplifier.

The MAX9717CEBL+T is a complete audio amplifier solution for high performance applications. It offers high performance and high power efficiency in a small package, and is suitable for a wide range of audio-related applications. Its features include a low-distortion Class-G output, a selection of three different output power levels, a low power shutdown mode, and PGA and S/PDIF input support. The device is ideal for use in high performance portable audio equipment, such as portable radios, mobile phones, portable music players, cellular phones and headsets, as well as automotive, studio and home audio applications.
