Hello chaps,
I've posted a schematic of a lm339 astable multivibrator driving a external circuit.
What I'ld like to know is what the resistors R3 and R5 are for.
I already know that it won't work without them.
Secondly, can anyone please be kind enough to post a schematic of a triangular wave generator using the lm339 chip? I've tried 2 schematics on proteus, one with a square wave generator feeding a integrator, but none give me a clean symmetrical triangle wave.
Thanks
