2.95W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION The IS31AP2005 is a high efficiency, 2.95W 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, IS31AP2005 is capable of driving 4Ω speaker load at a continuous average output of 2.95W with 10% THD+N. The IS31AP2005 has high efficiency with speaker load compared to a typical class AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the IS31AP2005. The gain of IS31AP2005 is externally configurable which allows independent gain control from multiple sources by summing signals from each function. The IS31AP2005 is available in DFN and MSOP packages. APPLICATIONS Wireless or cellular handsets and PDAs Portable DVD player Notebook PC Portable radio Educational toys USB speakers Portable gaming TYPICAL APPLICATION CIRCUIT FEATURES JULY 2011 5V supply at THD = 10% -2.95W 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 3mm × 3mm DFN-8 and MSOP-8 package RoHS compliant and 100% lead(Pb)-free
