hi i was just wondering does any body know can a 0 to 10 volt output be achieved by using either the lm 2917 frequency to voltage converter or the lm2907? i know the lm 2917 has a built in zener diode which has a value of 7.56 volts. does this limit your output voltage in that you can only get an output voltage of up to 7 volts to correspond with a given frequency??? or can a bigger output voltage be obtained by using the lm 2907 without the zener diode regulation? any help would be appreciated thanks.
