Hi
I'm trying to use the LM2917 IC as a frequency to voltage converter circuit. However I am unable to get a change in the output voltage which is proportional to the frequency. I have used the circuit given in the TI data sheet for LM 2917. The Fin is a 1kHz square wave with an amplitude of 5Vpp. The capacitance connected to pin 2 is 0.02 microF and the resistor connected to pin 3 is 560 kilo ohm. There is no change in my output voltage if I vary the frequency. I have tried this circuit with both the 8pin and 14 pin versions of LM 2917. Please help.
Thank You
