Does this have a coupling capacitor? I want to drive drive from an Arduino PWM pin

According to the data sheet this device is driven by a digital output, so no coupling capacitor would be required.

Hi Tepalia,

Looks like the amp chip is rated for 2W, but the speaker is only rated for 0.15W. Any other specs you were after?
