概觀
The IS31AP2036A 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 VCC supply.
The IS31AP2036A integrates advanced high efficiency
charge pump and whole power amplifier efficiency can
be up to 75%. The output power will be maintained in
0.8W, 1.0W and 1.2W.
The IS31AP2036A 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 IS31AP2036A use fully differential design to reduce
RF noise. The IS31AP2036A integrates de-pop circuitry
to reduce pop and click noise during power on/off or
shutdown enable operation. The IS31AP2036A also
integrates thermal and short circuit protection function.
IS31AP2036A is available in FCQFN-16 (2mm × 2mm)
package. It operates from 3.0V to 5.0V over the
temperature range of -40°C to +85°C.
