General Description
The MAX9710/MAX9711 are stereo/mono 3W bridge-tied load (BTL) audio power amplifiers. These devices are PC99/01 compliant, operate from a single 4.5V to 5.5V supply, and feature an industry-leading 100dB PSRR, which allows these devices to operate from noisy supplies without additional, costly power-supply conditioning. An ultra-low 0.005% THD+N ensures clean, low-distortion amplification of the audio signal while patented click-and-pop suppression eliminates audible transients on power and shutdown cycles. Power-saving features include low 2mV VOS (minimizing DC current drain through the speakers), low 7mA supply current, and a 0.5µA shutdown mode. A MUTE function allows the outputs to be quickly enabled or disabled.
