please help me confirm my thoughts (CEM3379 filter/VCA)

Ok, I'm pretty sure I've got this figured out, and under normal circumstances I would just wire it up & hope for the best, but considering the price of these chips I'm feeling more cautious- and since I'm still pretty new to this stuff, I'd rather ask a stupid question than fry something.

Anyway, my main question is this: the datasheet says "The maximum supply allowed across either device is 25 volts. Due to internal voltage regulators, the supplies do not have to be balanced: +5/-12 is allowed, as would be +12/-5. Since the maximum positive output swing of the filter is 2.9 volts below the positive supply, some loss in maximum VCF output will occur at +4.75 volt supply. For best performance with low power dissipation, use +9/-5 or +12/-5 supply voltages".

It seems to me that I should be able to power it from a +/-12V supply with no trouble, since that falls within the 25 volt range mentioned, is that correct?

Hi Slugger,

This datasheet:

http://www.datasheetarchive.com/CEM3379-datasheet.html

specifically points out that indeed +12V/-12V is an acceptable power supply.

Thanks for the confirmation. The datasheet was where I got my info, but the wording later on made me doubt myself. Being a bit of a n00b, I wanted to be sure I wasn't misunderstanding something.
