IS31AP2010F
2.8W@5.0V MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The IS31AP2010F is a high efficiency, 2.8W@5.0V
mono filter-less Class-D audio power amplifier. A low
noise, filter-less PWM architecture eliminates the
output filter, reduces external component count,
system cost, and simplifying design.
Operating in a single 5.0V supply, IS31AP2010F is
capable of driving 4Ω speaker load at a continuous
average output of 2.8W@10% THD+N. The
IS31AP2010F has high efficiency with speaker load
compared to a typical Class- AB amplifier.
In cellular handsets, the earpiece, speaker phone, and
melody ringer speaker can each be driven by the
IS31AP2010F. The gain of IS31AP2010F is externally
configurable which allows independent gain control
from multiple sources by summing signals from each
function.
IS31AP2010F is available in UTQFN-9 packages. It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
