Linear amplifiers are an essential part of any audio reproduction system in order to ensure a high-quality listening experience. The MAX9768BETG/V+ is a small, low-power audio amplifier that is designed to provide high-quality audio amplification in small form factor applications. This article will explore the MAX9768BETG/V+ application field and working principle.

The MAX9768BETG/V+ is a class D, stereo switchable, variable-gain amplifier housed in a tiny, 1.27mm x 1.27mm, 8-pin Flip-Chip package. The amplifier has a low shutdown current of only 19.5µA, with a low-power supply current and a wide 4.5V to 17V supply voltage range. The amplifier is capable of delivering up to 1.4W of stereo power output and is ideal for audio systems such as portable applications and automotive head units.

The MAX9768BETG/V+ also features a built-in high-efficiency filter-less modulation scheme that enables distortion cancellation and improved low-frequency performance. The amplifier has a programmable gain range of -12dB to 30dB, allowing it to be used in range of applications including personal audio devices, multimedia and mobile devices, precision audio test instruments, PA audio systems, and medical ultrasonic imaging equipment.

The working principle of the MAX9768BETG/V+ is that of an audio amplifier with an output stage consisting of a class D amplifier in closed loop configuration. The amplifier uses a high-performance PLL (phase-locked loop) to generate a train of pulses that are used to control the linearity and dynamic range of the class D amplifier. This results in a very low distortion, low noise, and wide dynamic range, especially in the bass region. The output of the class D amplifier is then filtered and buffered to provide the required output with minimal crossover distortion.

The MAX9768BETG/V+ includes a variety of additional features for improved performance. The amplifier is capable of pulse-by-pulse disabling of the output stage, enabling the amplifier to be turned off without having to power down the entire system. The amplifier also includes an internal shutdown and controller, which acts as a low power brake, and an onboard limiter that can be used to control the maximum output level and minimize distortion.

The MAX9768BETG/V+ is an ideal solution for audio systems requiring a high-performance amplifier with minimal power consumption in a small form factor. Its low noise and wide dynamic range makes it perfect for applications such as portable audio players, multimedia devices, medical ultrasound systems, and more. Its versatile gain range and power-saving features make it an ideal choice for any application where audio quality and power efficiency is a priority.
