The MAX9715 high-efficiency, stereo, Class D audio power amplifier provides up to 2.8W per channel into a 4Ω speaker with a 5V supply. Maxim's second-generation Class D technology features robust output protection, high efficiency, and high power-supply rejection (PSRR) while eliminating the need for output filters. Selectable gain settings, +10.5dB or +9.0dB, adjust the amplifier gain to suit the audio input level and speaker load.The MAX9715 features high PSRR (71dB at 1kHz), allowing for operation from noisy supplies without additional regulation. Comprehensive click-and-pop suppression eliminates audible clicks and pops at startup and shutdown. The MAX9715 operates from a single 5V supply and consumes only 12mA of supply current. Integrated shutdown control reduces supply current to less than 100nA.The MAX9715 is fully specified over the extended -40°C to +85°C temperature range and is available in thermally enhanced 16-pin TQFN-EP package.ApplicationsHigh-End Notebook AudioLCD ProjectorsMultimedia Docking StationsPortable Audio
