Afternoon All,
I have been tinkering with the circuit below to amplify output from a Piezo disk but need to make some tweaks - my knowledge is not up to speed with OP Amps so wondering if I can swing this one past you good folk for thoughts?
Basically the circuit has too much gain for my application and I am struggling to get the control I need from the POT as its all down one end - I guess the first question is what is the gain of this circuit and which resistors would I change to which values to say halve the gain?
The next question is speed, I think this circuit is designed for audio out so it has some capacitors which are smoothing the output signal I guess - if I am more interested in speed (ie I just want to see the output as quickly as possible after the input) can I just remove these to achieve this end or is there a better way? Also, any idea how I would know the time delay between input and output?
Thanks for any thoughts
