Key Featrues
Spread-Spectrum Mode: The unique spread-spectrum modulation reduces electromagnetic interference (EMI) by 5dB compared to conventional methods. This improvement ensures compliance with EMI regulations and enhances performance in noise-sensitive environments, such as automotive and consumer electronics.
High Efficiency (Up to 88%): With efficiency reaching 88% at 16Ω load, the amplifier minimizes power loss and heat generation. This makes it suitable for battery-powered devices and applications requiring energy efficiency, such as portable speakers and hands-free car phone adapters.
Low THD+N (0.07%): The amplifier delivers high-fidelity audio with a low total harmonic distortion plus noise (THD+N) of 0.07%. This ensures clear and accurate sound reproduction, enhancing the listening experience in applications like desktop PCs and LCD TVs.
Integrated Protection Features: The device includes short-circuit and thermal-overload protection, ensuring reliable operation under adverse conditions. These safeguards extend the lifespan of the amplifier and improve system reliability in demanding environments like industrial audio systems and automotive applications.
Applications
Hands-Free Car Phone Adapters: The MAX9704 is well-suited for hands-free car phone adapters, delivering robust audio performance with up to 15W mono output. Its high PSRR and differential inputs minimize noise from the vehicle's electrical system, ensuring clear communication even in noisy environments.
LCD Monitor Audio Systems: The MAX9704 is perfect for integrating into LCD monitors, offering 2x10W stereo output for high-quality audio. Its compact TQFN package and low quiescent current make it an excellent choice for space-constrained monitor designs, providing rich sound without compromising on efficiency.
LCD TV Audio Amplification: The MAX9704 is ideal for LCD TVs, delivering up to 15W mono or 2x10W stereo output for immersive audio experiences. Its spread-spectrum mode reduces electromagnetic interference, ensuring compliance with stringent TV audio standards while maintaining high efficiency and low distortion.
