Overview
The IS31AP2006 is a high efficiency, 3W 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, IS31AP2006 is
capable of driving 4Ω speaker load at a continuous
average output of 3W with 10% THD+N. The
IS31AP2006 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 IS31AP2006.
The gain of IS31AP2006 is externally configurable
which allows independent gain control from multiple
sources by summing signals from each function.
The IS31AP2006 is available in DFN-8 (3mm×3mm)
package.
