Part Number: LM2901
I need to design a signal conditioning board for a tachometer generator input. The input will be 3 Phase AC with variable frequency of 0 to 80Hz and amplitude 10V ( in each line).
As the motor RPM changes, frequency changes. Please suggest me a frequency to voltage converter IC for sensing the frequency change.
Thanks & Regards,
See the datasheet for the LM2907/LM2917 voltage-to-frequency converter:
