3W@5.0V MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER

April 2013

GENERAL DESCRIPTION

The IS31AP2010B is a high efficiency, 3W@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, 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.

FEATURES

 5.0V supply at THD+N = 10%

―3W into 4Ω (Typ.)

―1.68W into 8Ω (Typ.)

 Efficiency at 5.0V

―85% at 400mW with a 4Ω speaker

―88% at 400mW with an 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

 Portable gaming
