dc to ac help

Recommended Posts

If an ordinary 555 has a 15V supply, as an oscillator its output goes up to only about 13.8V and down almost to 0V. So the output is not 15VAC.

A Cmos 555 like an LMC555, TLC555 or ICL7555 has an absolute max supply voltage of 15V and its output will swing up to exactly 15V and down to 0V if it has a very high load resistance.

The outputs of a 555 and a Cmos 555 are square-waves.
