Working Principle of MAX9888EWY+T

The MAX9888EWY+T is designed to drive stereo headphones from mobile devices. It features an integrated linear-amplifier architecture, which provides a smooth frequency response from 10Hz to 20kHz. The audio signal is first filtered by a low-noise filter, which eliminates unwanted noise. Then, the signal is amplified by a Class-D headphone amplifier, which delivers a high headroom and high efficiency. Finally, the amplified signal is fed to the output stage, where it is further amplified and delivered to the headphones. In the case of a short circuit or overloaded signal, the device includes an anti-click circuitry, which eliminates pop and click noises while headphones are being connected to the device.

In addition, the headphone amplifier includes a mute input and three independent gain control pins, which can be used to adjust the output volume accordingly. The integrated ESD protection protects the device from damage caused by electro-static discharge.

Conclusion

The MAX9888EWY+T is a highly integrated, Class-D amplifier optimized to drive stereo headphones from mobile devices. It is designed for linear-amplifier audio applications, such as cell phones, portable media players, digital voice recorders, and other audio applications. The device features a low-power consumption, low quiescent current, high efficiency, high headroom, and a smooth frequency response from 10Hz to 20kHz. It also integrates a headphone-amplifier output stage, low-noise filter, and anti-click circuitry. Furthermore, it includes a mute input and three independent gain control pins to adjust the output volume accordingly.
