IS31AP2006 3W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER June 2017 GENERAL DESCRIPTION FEATURES The IS31AP2006 is a high efficiency, 3W mono 5V supply at THD= 10% Class-D audio power amplifier. A low noise, filter-less - 3W into 4 (Typ.) PWM architecture eliminates the output filter, reducing - 1.70W into 8 (Typ.) external component count, system cost, and Efficiency at 5V: simplifying design. - 83% at 400mW with a 4 speaker Operating in a single 5V supply, IS31AP2006 is - 89% at 400mW with an 8 speaker capable of driving 4 speaker load at a continuous Optimized PWM output stage eliminates LC average output of 3W with 10% THD+N. The output filter IS31AP2006 has high efficiency with speaker load Fully differential design reduces RF rectification compared to a typical Class-AB amplifier. and eliminates bypass capacitor In cellular handsets, the earpiece, speaker phone, and Integrated pop-and-click suppression circuitry melody ringer can each be driven by the IS31AP2006. DFN-8 (3mm3mm) package The gain of IS31AP2006 is externally configurable which allows independent gain control from multiple APPLICATIONS sources by summing signals from each function. Wireless or cellular handsets and PDAs The IS31AP2006 is available in DFN-8 (3mm3mm) Portable DVD player package.
