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 8speaker 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.
IS31AP2031 is available in QFN-20 (3mm × 3mm)
package. It operates from 2.7V to 4.5V over the
temperature range of -40°C to +85°C.
FEATURES
