GENERAL DESCRIPTION
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.

FEATURES
• 5V supply at THD = 10%
   -3W into 4Ω (Typ.)
   -1.70W into 8Ω (Typ.)
• Efficiency at 5V:
   -83% at 400mW with a 4Ω speaker
   -89% at 400mW with an 8Ω speaker
• Optimized PWM output stage eliminates LC
   output filter
• Fully differential design reduces RF rectification
   and eliminates bypass capacitor
• Integrated pop-and-click suppression circuitry
• DFN-8 (3mm×3mm) packages

APPLICATIONS
• Wireless or cellular handsets and PDAs
