i got a speaker i wanna put in my psp. i got a tda2822 chip. i wanna know how to wire it...i dont know anything about circuits. kindof a noob. the TDA2822 has 8 pins.....i wanna know how to wire it....with all the caps and diodes. thankz

hmm, how did you come up with the TDA2822 if you know nothing about circuits? I am not sure where to tie the amplifier into the PSP in order to accomplish this, however I can tell you how to figure the amplifier circuit:

That is your specsheet for that chip. If you look at page1 there is an application circuit and that is the circuit(or close to) that you want to build. There are no diodes, just resistors and capacitors. If you are only doing one speaker channel, only use one side of the device.
I believe the 10k resistor size will have an effect on your gain, not sure, that particular spec sheet doesnt elaborate very well.

the tda 2822 chip i got, has 8 pins...thankz alot for getting back to me. i got a sweet small speaker from an old Mac i wanna try useing....it bangs wit bass and treble. but i and clueless about wiring. yea a big noob.

oh sorry that spec sheet was for the PDIP version

Thats the correct version, but all the information is the same.
