IS31AP2005
2.95W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
December 2012
GENERAL DESCRIPTION
The IS31AP2005 is a high efficiency, 2.95W mono
Class-D audio power amplifier. A low noise, filter-less
PWM architecture eliminates the output filter, reducing
external component count, system cost, and
simplifying design.
Operating in a single 5V supply, IS31AP2005 is
capable of driving 4Ω speaker load at a continuous
average output of 2.95W with 10% THD+N. The
IS31AP2005 has high efficiency with speaker load
compared to a typical Class-AB amplifier.
In cellular handsets, the earpiece, speaker phone, and
melody ringer can each be driven by the IS31AP2005.
The gain of IS31AP2005 is externally configurable
which allows independent gain control from multiple
sources by summing signals from each function.
The IS31AP2005 is available in DFN-8 and MSOP-8
packages.
FEATURES
5V supply at THD = 10%
-2.95W into 4Ω (Typ.)
-1.70W into 8Ω (Typ.)
Efficiency at 5V:
-83% at 400mW with a 4Ω speaker
-89% at 400mW with an 8Ω speaker
Optimized PWM output stage eliminates LC
output filter
Fully differential design reduces RF rectification
and eliminates bypass capacitor
Integrated pop-and-click suppression circuitry
Short-circuit and thermal protect
3mm × 3mm DFN-8 and MSOP-8 package
RoHS compliant and 100% lead(Pb)-free
APPLICATIONS
Wireless or cellular handsets and PDAs
Portable DVD player
Notebook PC
Portable radio
Educational toys
USB speakers
Portable gaming
