MAX9715 pdf datasheet

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 a
thermally enhanced 16-pin TQFN-EP package.
