[sdiy] CEM3360 tolerances

[Schwarz Raphael]

Hello Everyone!

Anybody has some experience with the CEM3360 VCA ?

http://www.alfarzpp.lv/eng/sc/AS3360.pdf <http://www.alfarzpp.lv/eng/sc/AS3360.pdf>

Seems almost too easy .

The datasheet specifies a control voltage from 0 to 2.08 V maximum, however it doesn’t specify anything for negative voltages 

There are few schematics in the modular realm for this one except for two digisound modules 

This one seems like a good example
http://www.digisound80.co.uk/digisound/modules/80-19_files/80-19.pdf <http://www.digisound80.co.uk/digisound/modules/80-19_files/80-19.pdf>

There seems to be no protection against any negative voltage on the control input , except from the voltage divider bringing everything within a 2V amplitude
My guess is there is not enough current to damage the chip with negative voltages but I want to be sure before i start burning chips.

Thanks !
