19-3589; Rev 2; 7/08 EVALUATION KIT AVAILABLE 2.8W, Low-EMI, Stereo, Filterless Class D Audio Amplifier MAX9715 General Description Features The MAX9715 high-efficiency, stereo, Class D audio 5V Single-Supply Operation power amplifier provides up to 2.8W per channel into a4 speaker with a 5V supply. Maxim s second-generation Patented Spread-Spectrum Modulator Reduces EMI Class D technology features robust output protection, 2.8W, Class D, Stereo Speaker Amplifier (4) high efficiency, and high power-supply rejection (PSRR)while eliminating the need for output filters. Selectable Filterless Class D Requires No LC Output Filter gain settings, +10.5dB or +9.0dB, adjust the amplifier High PSRR (71dB at 1kHz) gain to suit the audio input level and speaker load. 86% Efficiency (R The MAX9715 features high PSRR (71dB at 1kHz), L = 8, POUT = 1W) allowing for operation from noisy supplies without addi- Low-Power Shutdown Mode tional regulation. Comprehensive click-and-pop sup- Integrated Click-and-Pop Suppression pression eliminates audible clicks and pops at startupand shutdown. The MAX9715 operates from a single 5V Low Total Harmonic Distortion: 0.06% at 1kHz supply and consumes only 12mA of supply current. Short-Circuit and Thermal Protection Integrated shutdown control reduces supply current toless than 100nA. Internal Gain, +9.0dB or +10.5dB The MAX9715 is fully specified over the extended Available in Space-Saving Package -40°C to +85°C temperature range and is available in a 16-Pin Thin QFN-EP (5mm x 5mm x 0.8mm) thermally enhanced 16-pin TQFN-EP package.
