Dave said:Hello,
I want to compare 2 signals. If one signal is higher than the other then I
want to output a logic zero, otherwise output a logic one. The signals will
be at no more than 12MHz with a maximum voltage of 5V. Do any chips exist
that will do this for me?
Yes, there is a chip called a comparator. It has two inputs: inverting
input (usually marked "-") and non-inverting input (usually marked "+").
If the inverting input is higher the output will be low, and if the
non-inverting input is higher the output will be high.
Maxim, and others, make these have a look at:
