IS31AP2005 - ISSI
IS31AP2005 . MONO FILTER-LESS CLASS-D audio power amplifier . September 2015. GENERAL DESCRIPTION FEATURES. The IS31AP2005 is a high efficiency, mono 5V supply at THD = 10%. Class-D audio power amplifier . A low noise, filter-less - into 4 (Typ.). PWM architecture eliminates the output filter, reducing - 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, IS31AP2005 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 with 10% THD+N. The output filter IS31AP2005 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 IS31AP2005 .
