The MAX9722BETE+T is a low power, energy efficient Class-D amplifier. It fits into BGA packages and is designed to drive small, medium and large current loads in a wide range of applications, such as laptops, smart watches, mp3 players, cell phones and tablets. The main feature of the MAX9722BETE+T is its high headphone drive capability and its low quiescent current. It integrates a power boost circuit in order to provide a maximum current boost of up to 16 times the original current drive.

The Class-D amplifier is an efficient way of converting a low voltage signal into a high current output. This can be used to drive headphones and other audio devices. The Class-D amplifier uses pulse width modulation (PWM) to convert the analog input signal into a digital PWM signal which is then amplified by a high-speed MOSFET output stage. This type of output topology is highly efficient, as it eliminates the need for bulky, expensive transformers and linear power supplies.

The MAX9722BETE+T can be used in applications such as headphone amplifiers, Class-D audio amplifiers, speaker drivers and DC motor controllers. It is also suitable for driving piezoelectric actuators and can be used to drive small loads such as headphones. The operating voltage for the MAX9722BETE+T is between 2.5V and 5V. The quiescent current of the IC is around 25 uA.

The MAX9722BETE+T has a differential input with a single-ended ground return configuration. The differential input provides better noise immunity, while the single-ended ground return allows the IC to be used with a wide variety of system voltages and power requirements. The input range of the IC is between 0.3Vrms and 3.3Vrms. The output power of the IC is also adjustable and can be set between 0.8W and 5W.

The MAX9722BETE+T also provides a configurable output gain, which can be set between 2.0 and 10.0 dB. Additionally, the IC comes with an integrated dynamic microphone Bias supply, which can be used for configurable low-power mic applications. The IC provides a high-quality headphone output and a low-noise output suitable for active speaker systems.

The MAX9722BETE+T offers a wide range of features, making it suitable for many audio applications. It operates from a single battery cell and is available in a small four-ball package, making it a great choice for applications where space is limited. Its low quiescent current and high headphone drive capability make it an ideal solution for portable audio applications.
