GENERAL DESCRIPTION
The IS31AP2036 is a Class-K audio power amplifier with
high efficiency and automatic gain control. It drives up to
2.0W (10% THD+N) into an 8Ω speaker from a 4.2V V_CC
supply.
The IS31AP2036 integrates advanced K-charge pump
which increases efficiency up to 92% and whole power
amplifier efficiency to 75%. The output power will be
maintained in 0.8W, 1.0W and 1.2W.
The IS31AP2036 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 IS31AP2036 use fully differential design to reduce
RF noise. The IS31AP2036 integrates de-pop circuitry to
reduce pop and click noise during power on/off or
shutdown enable operation. The IS31AP2036 also
integrates thermal and short circuit protection function.
IS31AP2036 is available in FC-16 (2mm × 2mm)
package. It operates from 3.0V to 5.0V over the
temperature range of -40°C to +85°C.
