i'v got a micro chip from an old cd drive. i wanna make an amplifier and i was wondering is it equivalent to lm386? Answered

i'v seen the cd audio amplifier instructable but i ripped it apart long ago. surprisingly i'v got the micro that's why i was asking if they are the same purpose.

No.

The LM386 is a mono low power audio amplifier designed to output into headphones or a small loudspeaker.
The final stage of a CD drive outputs a stereo signal which is designed to go into the line inputs of an amplifier; so whatever you've got the impedance is wrong, the power level is wrong and the voltage is wrong.

Go on. treat yourself to a LM386! There's several circuits over there ----->

hey! I'v also got a TDA2822 CHIP FROM A mini radio. Does that help?

Yep, there's a power amp for you. For anything else, just enter the part number with 'datasheet' after it to get information on the chip.


Which one? What is the part number?
