Other Parts Discussed in Thread: UAF42, LM4766
In my circuit depicted below, I am applying a voltage of 3.3 volts through a programmable crystal to trigger a ripple counter to pass a voltage onwards. In the layout, I have used the same 3.3 volts to power the ripple counter via Pin16.
I have no knowledge of electronics, and thus I wonder, if it is possible to use my supply voltage of 15volts to trigger Pin16 whilst my voltage from the crystal is typically less than 3.3 volts going to Pin11?
The other question relies on the reply to my first question but if I must use the same 3.3 volts to power the ripple counter via PIn16, can I add a MOSFET to the output from the ripple counter to allow a greater voltage to be passed on to the next part of the circuit which is a UAF42 square wave to sine wave converter, which in turns then goes to a LM4766 Amplifier?
If I can add a MOSFET, is it possible for someone to give me a sketch, please, of how it should be connected?
I would be most grateful for your help.
Thank you so very much.
