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.

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 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
