Sorry. Maybe this is a newbie question. I have seen lots of mp3 player projects using direct output of DAC to drive headphones. But does the DAC provide enough power to drive the speakers? Or do i have to amp the DAC output and then drive the speaker.
 

Yeah you need the amplifier, otherwise you will burn your DAC

a simple amp you can built is with TDA810, or there are many.
but its must to have amp
 

Generally, it is necessary to use an AMP to drive speaker or headphone, actually there is a Power AMP intergrated into chips (after Audio DACs line out). however if driving headphone load only, the output power is much smaller, it is enough if there is 30~50mA source/sink capbility, exg, opamp.
 

Some audio DAC can drive headphones. For speakers, you probably need a dedicated driver.
