IS31AP2010E
MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
Advanced Information
May 2012
GENERAL DESCRIPTION
The IS31AP2010E is a high efficiency, 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.
In cellular handsets, the earpiece, speaker phone, and
melody ringer speaker can each be driven by the
IS31AP2010E. The gain of IS31AP2010E is externally
configurable which allows independent gain control
from multiple sources by summing signals from each
function.
IS31AP2010E is available in UTQFN-9 packages. It
operates from 2.7V to 5.5V over the temperature range of
-40°C to +85°C.
FEATURES
Supply voltage from 2.7V ~ 5.5V
High efficiency
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
Portable gaming
