Hi everyone,

I need some help from all of you for my project. I've been doing a project that using strain gauge. and I want to make a op Amp circuit that I'll be used for amplified my strain gauge sensor and I use AC voltage to drive my wheatstone bridge.
I will use the single supply 5 volt with frequency 2000KHz.

If all of you have any suggestion it would be very nice for me.

Thank you before.

Read that application note. You may wish to keep your excitation frequency a bit lower than 2kHz. The higher in frequency you go, the more trouble you will have with parasitic L and C.
