The MAX9728BEUD+ is a high-performance, low-voltage stereo audio processor with a Class AB headphone amplifier that supports both analog and digital inputs. The audio processor’s integrated digital signal processor (DSP) provides level-shifting, compensation, and times 4 or 8-channel input processing. The headphone amplifier features high output power, low noise, and low distortion. The processing is well suited for driving high-impedance headphones, including 50-ohm headphones, and earbuds.

Application Field

The MAX9728BEUD+ can be used in many applications, such as mobile phones, personal computers, portable media players, digital cameras and audio docks. It also can be used in game consoles, TVs, audio players, car audio, and even home audio systems. This audio processor is ideal for boosting the sound level and adding richness to the sound quality of various audio devices. It also supports both analog and digital inputs, allowing you to enjoy the complete audio experience.

Working Principle

The MAX9728BEUD+ utilizes a Class AB headphone amplifier for efficient power delivery and low-noise operation. The amplifier is embedded in the board and allows for the ability to boost the audio signal from a variety of different sources. It also supports input signals of up to 6.8 dBV, allowing it to handle output levels that are substantially higher than what is typically seen. The integrated analog-to-digital converters (ADCs) can also be configured to support various sample rates and bit depths. This ensures that the audio quality will not be degraded due to the digitalization process.

The integrated DSP provides a number of different levels of audio processing, including level-shifting and compensation, as well as provides times 4 or 8-channel input processing. This type of multi-channel processing ensures that the sound quality is consistent across all input channels. The processor also supports a wide range of audio formats, including MP3, AAC, and others. The integrated gain blocks also provide the ability to easily adjust the sound level without affecting other portions of the audio chain.

The MAX9728BEUD+ also features a headphone amplifier that provides a high output power, low-noise, and low distortion. This ensures that the audio output from the device is of the highest quality and is consistent across all input signals. The amplifier also features an integrated thermal sensor, which ensures that the amplifier will not get too hot and cause any damage. Additionally, the headphone amplifier also has various other features that allow it to operate efficiently and provide the highest level of audio performance.
