General Description
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 addi-
tional regulation. Comprehensive click-and-pop sup-
pression 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.
