Hello.
I'm planning to use an accelerometer to sense small vibrations over a BW of 2kHz. This accelerometer can output 1000mV/g so it's quite sensitive. Anyways.
I have these three outputs and I feel that the output will be of small value because the vibration is not that very high. That means I must use some sort of operational amplifier.
I was suggested to use an instrumentation amplifier for this purpose since they have very low noise and works very well.
Anyways, my problem is the instrumentation amplifier part. I have not worked with amplifiers before and some help would be grateful. There's a plus and a minus input on this amplifier. How do I connect the accelerometer to amplify these signals? Instrumentation amplifier works by amplifying the difference between two sources if I have understood this correctly. Ddo I connect the X signal to plus and ground to minus so X is amplified?
Sorry if this is a stupid question. But I have very Little experience with OP-amps and as much as I read about them, I just cannot grasp them really well.
Thanks!!
