It is predicated on a state-of-the-art Class-D audio amplification architecture that provides optimal performance with a power output of up to 2 W. This audio amplifier integrated circuit is designed for typical consumer applications, such as portable electronics and consumer audio products. The MAX9719DEBE+ provides a high level of integration and simplifies the design process for consumer audio products.
Features of MAX9719DEBE+
The MAX9719DEBE+ stereo digital input Class-D audio amplifier integrated circuit offers several features that enable the design and implementation of efficient, high-quality audio products.
- Low-Noise, Low-Distortion Audio Output: The MAX9719DEBE+ is able to deliver low-noise and low-distortion audio output. This makes it suitable for a wide range of end applications and provides excellent sound output quality.
- High Light and Load Output Capabilities: The MAX9719DEBE+ can drive up to 2 W of output power into an 8 Ω load. It also features a high level of light output and is able to drive loads up to 90% of its maximum output power. Additionally, the device can be adjusted via current sink and source pins to drive up to 4 W of output power into a 4 Ω load, making it very flexible for application designs.
- Selectable Audio Inputs: The MAX9719DEBE+ has two selectable audio inputs, one for each channel. It supports PCM, I2S and DSD, allowing for a wide range of audio signals to be processed.
- Advanced Shutdown Modes: The MAX9719DEBE+ features several advanced shutdown modes, making it an ideal choice for applications such as portable electronics. It can be operated in ultra-low-power mode, shutdown mode, and standby mode.
Applications
The MAX9719DEBE+ is ideal for applications such as loudspeakers, soundbars, audio amplifiers, headsets, and mixers. It can be used in both portable and non-portable applications due to its low-power consumption, small size, and high efficiency. Additionally, the device is designed for automotive applications and provides protection against electrostatic discharge (ESD).
Working Principle
The MAX9719DEBE+ is a Class-D audio amplifier that works on the principle of pulse-width modulation (PWM) to achieve high efficiency. The amplifier works by modulating the width of the pulses to control the output power and sound. The input signal is sent to an analog low-pass filter, which eliminates any high frequency noise that could affect the output signal. The signal is then sent to the MOSFET (metal-oxide-semiconductor field-effect transistor) pairs, which switch on and off at a high frequency (typically 50kHz to 200 kHz) to create the pulse-width modulated signal. The output of the amplifier is then filtered to remove any high frequency content before being amplified and sent to the loudspeaker.
Conclusion
The MAX9719DEBE+ stereo digital input Class-D audio amplifier integrated circuit from Maxim is a versatile and efficient device for audio applications. It provides excellent performance and sound quality, while offering a high level of integration and simplifying the design process. Additionally, the device has advanced shutdown modes and is suitable for use in automotive applications. The MAX9719DEBE+ is an ideal choice for applications such as loudspeakers, soundbars, headsets, mixers, and audio amplifiers.
