IS31AP2006 Datasheet | ISSI

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 ponent 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 pared to a typical class-AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the IS31AP2006. The gain of IS31AP2006 is externally configurable which allows independent gain control from multiple sources by summing signals from each function. The IS31AP2006 is available in DFN-8 (3mm×3mm) packages. Features - 5V supply at THD = 10% -3W into 4Ω (Typ.) -1.70W into 8Ω (Typ.) Efficiency at 5V: -83% at 400m W with a 4Ω speaker -89% at 400m W 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 Portable DVD player Notebook PC Portable radio Educational toys USB speakers Portable gaming TYPICAL APPLICATION CIRCUIT http://..net/ Figure 1 Typical Application Circuit (Differential Input) Integrated Silicon Solution, Inc. - .issi.
