Thanks for the welcome to the Forum!

I am having some difficulty with a problem which I am trying to solve:

I have a sensor which outputs a voltage either between 0-5V or 0-12V on a logarithmic basis. I now want to display a value corresponding to the voltages on a 3 digit seven segment display which will show the percentage of gas the sensor picked up.

I have seen that the LM3915 can interpret this logarithmic signal, but am not sure if it can actually drive 7 segment displays?

I have also looked at the ICL7106 and TC7106A ICs but they do not seem to be able to deal with logarithmic input signals.

Thanking you all in advance!

Kind Regards,

P.
