The MAX9768BETG/V+T is a high-performance, low-noise, low-distortion, stereo-audio Class-D power amplifier. Its power gain enables it to directly drive speakers, providing high-power efficiency and reducing operating costs. This low-voltage Class-D amplifier can power speakers with input power up to 1.5 Watts without an external audio pre-amplifier. The MAX9768BETG/V+T features differential inputs for enhanced noise immunity, 2.5VRMS line output capability, low-pass filter, and internal gain settings from 6dB to 36dB. It also features over-current protection and thermal protection for improved reliability. The MAX9768BETG/V+T offers adjustable gain control for a wide-range of applications.

The MAX9768BETG/V+T application field is mainly the audio and electronic playback system, such as high-end multimedia speakers, portable audio players, audio frequency karaoke players, computers, and other audio playback systems. The MAX9768BETG/V+T is suitable for applications requiring low-noise, high-performance, and high-power-output audio power amplifiers.

The working principle of the MAX9768BETG/V+T is to convert the input signal into a pulse-width-modulated (PWM) signal and then perform the conversion in two stages. In the first stage, the PWM signal is used to drive an applifier comprising two MOSFETs. In the second stage, the amplified signal is fed to a high-side and a low-side MOSFET driver, one for each MOSFET, which then drive the speaker.

The MAX9768BETG/V+T has an adjustable gain control, so it can produce audio output of different level and quality. It also has a low-pass filter, which is used to reduce the level of short-term distortion in the audio output signal. The amplifier also has an over-current protection and thermal protection, which help ensure safety during operation.

The MAX9768BETG/V+T is a great choice for audio applications that need a high-power, low-noise, low-distortion, stereo-audio Class-D amplifier. It has a wide range of features that make it suitable for a variety of applications, from high-end multimedia speakers to portable audio players and audio-frequency karaoke players. Its low-voltage Class-D design enables it to efficiently drive speakers and provides reliable operation in the most demanding audio applications.
