I'm trying to convert a voltage that is between -5V and +5V to the range of 0...5V. That's possible with the schematics found at [https://masteringelectronicsdesign.com/design-a-bipolar-to-unipolar-converter/][1] With a TL074 opamp this works fine on my breadboard. [1]: https://masteringelectronicsdesign.com/design-a-bipolar-to-unipolar-converter/ Now there is a problem with that: the input-voltage for my use-case (eurorack/a100 modules) *can* be -12...12V in some cases. In that case (e.g. anything that is outside -5...5V) I would like to clamp it to -5...5V. Limitting to +5 I can do with a LM336Z-5.0 I think but how can I protect against voltages lower than -5V? (or less than 0V after conversion) The signal I'm converting is an audio-signal.
