While these will work, an Instrumentation amp will be better. They are generally considered to be "unique op amps" since they provide the same functions of an op amp but provide better performance.Try TL071/NE531/LF351/TL081 all are low noise, hi performance op-amps. Get a low noise op amp for your application. 741 is a general purpose, compensated op amp.
Once you have boosted the output of the accelerometer adequately, what is your plan for the output of the signal? How do you intend to use the output?For the sensitivity yes im interested in 2g's but i wont be using a micro controller.
Ive been trying to recreate the circuit in this website (http://www.me.utexas.edu/~dsclab/labs/accelerometers/ex2.html) varying the resistors according to my gain calculation, but Ive had little success. Any ideas, thanks.
If you are supposed to get oscillations, I would hook the output of the device to an oscilloscope. Then you can see if your getting a applicable waveform corresponding to the correct waveform.If I get this to work.. Im supposed to be measuring small oscillations. kinda like just put the accelerometer on the end of a ruler and pluck the ruler. a small cantilever beam, i want to get the sinusoidal wave for a long beam.
