Re: Peak Hold or Peak Follower OpAmp Ckt

Thanks To All I Did come up with a Peak Follower Ckt with the diodes, I used a small sig FET to discharge the Cap it works well, but I still need to work on it some more I was seeing the peak and the follower voltage tracking but there was some droop on the follower ckt (? Caps old mica) Will post C...

Re: Peak Hold or Peak Follower OpAmp Ckt

I'm looking to catch 1µSec., 5V max, AC pulse peek at a rate of 60Hz.
The pulse is 8µSec. to 13µSec. after high going trigger pulse. (noise from 3.5µSec. to 4.5µSec.)
Then read ADC to get the value.
All run buy a Basic Stamp or PIC.

Thanks
