I need to PWM audio signals. I've been told there is an ic that will do it: put the signal in and get out the modulated pulses. does anybody know of such an ic and point me to a datasheet ?
thanks

Thunderchild said:great, just read the damn question. what is a class D amplifier I only know of A AB B and C. all i want in udio in PWM out just that simple. the 555 should do this but I sdon't think it will work very well and a friend told me there is a specific PWM IC but he couldn't remember the name of it
Thunderchild said:hey all sorry I was a bit fed up the other day please exscuse me I'm not normally liek that it's just that I seem to run around in blasted circles. As it is so difficult to get parts here in Italy I want to make a generic pw modulator that i can use for anything from motor speed control to audio amplifiers 1 w to 100 watts. that way instead of waiting six months for this IC and that IC i just work out a generic pwm and use the apropriate driving mosfet.
