Hy, I am analyzing a signal conditioning circuit that is connected to a ICP accelerometer. The accelerometer is directly connected to the IN net
The circuit has a input filter connected to a programmable gain amplifier and an output filter conncted to the input of a ADC.
Concerning the input filter I am in doubt how to calculate the cutoff frequency for the presence of the resistor R1 and the capacitor C2( I guess that it has only a function of bypass and it does not have influence on the input frequency filter).
Concerning the output filter I am in doubt how to calculate the cutoff frequency for the presence of the resistor R6. (Without the resistor R6 the cutoff frequency should be 1/(2*pi*R4*C3) = 3120Hz )
I attach the schematic of this session
Thanks in advance
