Hello alltogether,
I am new at analog circuit design and want to amplify a differential voltage from a push-pull wheatstone brigde. I will use an Instrumentation Amplifier for this purpose. The differential signal has a high Bandwidth (3 MHz), so i can`t set a high gain in my In-Amp (lets say it will be 5 with 3 MHz Bandwidth), because the In-Amp-Bandwidth (BW) decreases with higher gain.
Is it possible to use the gain of 5 and amplify the In-Amp-output-signal with a single ended OP-Amplifier with a higher Gain (so my overall gain is 5*(gain of OP-Amp))?
Sry for my bad english.
Thank you,
Regards,
Lyto
