IS31AP2036A-CLS2-EB: 2W @ 8Ω, Class K, 3 ~ 5V in

Summary

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 speakerfrom 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 demo board has four modes to test the functionality of the IS31AP2036A.
