MAX9789AETJ+T is one of the top-of-the-line linear amplifiers designed and manufactured by Maxim Integrated. It is used in a wide range of audio applications, such as portable entertainment devices, high-end home theater systems, and professional audio systems. The device is designed to be extremely efficient and delivers full 20W of power with >90% efficiency in a very small application board.

The MAX9789AETJ+T amplifier is based on a Class D architecture and employs a unique monolithic composite amplifier topology. It includes two switching amplifiers integrated into the same die, one for the low-frequency range and another for the high-frequency range. The high-frequency switching amplifier is configured as a dual-mode amplifier, with the gain switchable between -16 and -26 dB. This provides an extra-wide gain range and makes the amplifier suitable for a wide variety of audio applications.

The amplifier has two separate power-supply stages, one for the low-frequency range and one for the high-frequency range. The low-frequency power-supply stage ensures that the signal is clean and quiet, while the high-frequency power-supply stage ensures high efficiency and fast distortion-free performance. The amplifier also features clock-noise cancellation and power saving modes to reduce power consumption. The amplifier is protected against short-circuits, thermal shut-down, and under-voltage.

The amplifier has low output noise, flat frequency response, and low distortion. It can output 1W of power with >90% efficiency and can go up to 20W with >85% efficiency. It also has a wide dynamic range and is capable of delivering true, undistorted sound. The high efficiency of the amplifier translates into high power-to-size ratio for small-form-factor applications.

The MAX9789AETJ+T amplifier is a high-performance Class D amplifier that is ideal for a wide range of audio applications. It offers high power output with low distortion, wide dynamic range and outstanding efficiency. Its dual-mode configuration provides for extra-wide gain range, making it suitable for a variety of applications. It also features clock-noise cancellation and power-saving modes to reduce power consumption. Overall, the MAX9789AETJ+T amplifier is a great choice for many audio applications.
