MAX9711ETC+

The MAX9711ETC+ is a 3W mono bridge tied load (BTL) audio power amplifier with shutdown in 12 pin TQFN package. Device is PC99/01 compliant, operates from a single supply and features an industry leading 100dB PSRR which allows it to operate from noisy supplies without additional, costly power supply conditioning. An ultra low 0.005% THD+N ensures clean, low distortion amplification of audio signal while 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 outputs to be quickly enabled or disabled. It is used in notebook PCs, flat panel TVs, flat panel PC displays, two way radios, general-purpose audio and powered speakers.
