Hi
I am building a simple F-V based on the application circuit in the datasheet which I modified resistor/capacitor values to suit my application.
I want my max frequency of 300Hz to give an output of 10V. My Vcc is 12V.
See attached schematic

The problem I am having is that the output voltage level reaches a maximum of 6.22V and refuses to go to 10V. I have tried playing with C and R but with no luck.
Please advise.
Kind Regards,
Student SA
