General Description

The IS31AP2010E is a high efficiency, 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.

In cellular handsets, the earpiece, speaker phone, and melody ringer speaker can each be driven by the IS31AP2010E.

Overview

IS31AP2010E MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER Advanced Information May 2012.

Key Features

  • Supply voltage from 2.7V ~ 5.5V High efficiency 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 Integrated click-and-pop suppression circuitry UTQFN-9 package RoHS compliant and 100% lead(Pb)-free.
