Hi.
I am currently working on FTV projects. I am using TC9400 to convert frequency to voltage and TL071 to get rid of ripple and ADC output.
I am using single supply for both case.
May I know how should I modify the TL071 to be 10v-GND?
Is there any additional circuit? ???
Attach on left is the circuits that I am working on, on right is the inverting single supply opamp taken from audioguru.
Thanks in advance. :)

Thanks for your help. ;)
Somehow, I face another problem dealing with my TC9400 :-\. It is a frequency to voltage IC from MICROCHIP. I had inputed the frequency supply at pin 11, and the result get at pin12 is very low.
The frequency input is 4k, 10k, 20k, 40k; I get more or less around 1.23v.
Is the diagram wrong?
Thanks.
