I am working on a device that looks a bit like a tablet. It consists of a display and a software controlled by touch on it. It uses the SAMA5D3 MCU from Atmel running linux.
I decided to implement audio to give the device a little bit more responsiveness and to be able to do some fancy text-to-speech stuff. I donít have space for large speakers, I found a few nice small SMD speakers around 500mW that I want to use.
I selected the well-known VS1053B as the CODEC chip. VS1053 has 3 output lines, LEFT, RIGHT and GBUF.
Can I connect the SMD-Speakers (500-800mW) directly to LEFT and RIGHT, or do I have to implement an amplifier like this one: MAX98306?
How to connect the speakers? One speaker + to LEFT, the other speakers + to RIGHT and both speakers Ė to GBUF?
If I just want to use one speaker, can I connect LEFT to RIGHT?
Thanks for your help?
