Ah theres a 32K resistor built in the output of the accelerometer so I removed the 34K resistor and directly connected the accelerometer output
No luck...
Also I'm using a signal generator with 50 ohm impedance (adjustable 50ohm or 600ohm switch) sweeping different frequencies into the input of the 34K resistor input to the differential input of the opamp
would I still need the buffer (voltage follower) for both tests?
seems like its acting like a bandstop filter, lowest amplitude where it should be largest, and outside frequencies get amplified
The simulation in both MultiSIM and LTSPice works correctly though
seems to be the 330nF ceramnic capacitors I used
When I use Ceramic caps, it doesn't work, it works opposite has a band stop filter and amplifies higher frequences, if I use tantulum capacitors it works CORRECTLY, but they are polarized, and also drift the signal as they charge and discharge
What caps should I be using, and why does ceramic caps not work?
