IS31AP2031 CLASS-G AUDIO POWER AMPLIFIER WITH INTEGRATED CHARGE PUMP CONVERTER January 2012 GENERAL DESCRIPTION The IS31AP2031 is a Class-G audio power amplifier with automatic gain control. It drives up to 2.0W (10% THD+N) into an 8Ω speaker from a 4.2V VDD supply. The IS31AP2031 provides low cost, space saving solution for portable equipments which need audio output with higher power by boosting up supply voltage. Its external components just include a few capacitors and resistors (no inductor). The IS31AP2031 use fully differential design to reduce RF noise. The IS31AP2031 integrates de-pop circuitry to reduce pop and click noise during power on/off or shutdown enable operation. The IS31AP2031 also integrates thermal and short circuit protection function.
