Convert integrator output analog 12V -> 0V to 0V -> 5V (analog)
I've got to convert the analog output of an integrator that sits nominally at 12V and goes to 0V for maximum drive ( the integrator actually goes to -12V but below zero doesn't matter). I have to scale this analog voltage to 0 to 5V. i have designed a Deboo integrator and realized that I would now have a reset problem so I designed a voltage scaler
To complete this I have an opamp that has +12/-12V supplies and the bandwidth of the circuit doesn't need to exceed 10kHz
Here's the LTspice circuit - The image on the left is without a zener to clamp the 0->5V output, the image on the right is with a 4.7V zener
Are there better ways to do this?
What issues might I run into with this implementation?

I suppose that I could just tie the positive rail of the op amp to +5V and the negative rail to ground, this would prevent out of bounds values on the output
