H90 CV Input Range

[jimfowler]

What does the H90 do with control voltages over 5V?  I’ll need to build a thing to scale the CV range of my modular (0-10V) but want to be sure I won’t damage anything if the 5V upper range limit is exceeded.

Thanks.

For voltages over 5, the H90 will just clip to 5V. Up to 12V shouldn’t damage anything, but I would not suggest you go past that (especially if it might be sustained).

thanks.  that was my assumption but wanted to clarify.

I think you could use a voltage divider or a protection circuit to limit the input voltage to around 0-5V before feeding it to the H90. Could that be correct?

Since the H90 provides over-voltage protection I will indeed build a simple divider to scale the CV input by 50%.  None of the devices in my modular system provide any voltages over 10V.
