Hello,
Here is my dilemma, when applying a low signal (near ground), my output of the LM2907 is not zero and the voltage varies,
I am using the tachometer with minimum component.
My voltage supply is 12.5V
R1 = 100K
R2 = 10K
C1 = 0.1uF
C2 - 1uF
the device is very linear and works from a frequency input of 3 - 30Hz. But when a low ground signal is applied, my output is not at zero.
Thanks, for the help.
