The MAX9715ETE+ is a 2.8W, low EMI, stereo, filterless class D audio amplifier in 16 pin TQFN package. This high efficiency, stereo, class D audio power amplifier provides up to 2.8W per channel into a 4ohm 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 audio input level and speaker load. It 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 start-up 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. Typical applications include high end notebook audio, LCD projectors & multimedia docking station
- Supply voltage range is 4.5V to 5.5V
- Operating temperature range from -40°C to 85°C
- Spread spectrum modulator reduces EMI
- Efficiency is 86% (RL = 8ohm, POUT = 1W)
- Low total harmonic distortion of 0.06% at 1KHz
