IS31AP2005
2.95W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
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 and MSOP
packages.

Differential Input and Single-Ended Input Signals
Summing Two Single-Ended Input Signals
The gain and corner frequencies (fC1 and fC2) for each
input source can be set independently (see equations
(11) through (14), and Figure 16). Resistor, RP, and
capacitor, CP, are needed on the IN- terminal to match
the impedance on the IN+ terminal.
The single-ended inputs must be driven by low
impedance sources.
