IS31AP2010B
[email protected] MONO FILTER-LESS, CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The IS31AP2010B is a high efficiency, [email protected]
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.

FEATURES
5.0V supply at THD+N = 10%
―3W into 4Ω (Typ.)
―1.68W into 8Ω (Typ.)
Efficiency at 5.0V
Operating in a single 5.0V supply, IS31AP2010B is
capable of driving 4Ω speaker load at a continuous
average output of 3W@10% THD+N. The
IS31AP2010B 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
IS31AP2010B. The gain of IS31AP2010B is externally
configurable which allows independent gain control
from multiple sources by summing signals from each
function.
IS31AP2010B is available in UTQFN-9 packages. It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
―85% at 400mW with a 4Ω speaker
―88% at 400mW with a 8Ω speaker
Less than 1μA shutdown current
Optimized PWM output stage eliminates LC
output filter
Fully differential design reduces RF
rectification and eliminates bypass capacitor
Improved CMRR eliminates two input coupling
capacitors
Integrated click-and-pop suppression circuitry
UTQFN-9 package
RoHS compliant and 100% lead(Pb)-free
APPLICATIONS
Wireless or cellular handsets and PDAs
Portable DVD player
Notebook PC
Portable radio
Educational toys
