[sdiy] LM358 datasheet VCO on spilt rails

[Dave Kendall]

Hi All.

Wondering if any of you have tried the VCO on page 1 of the National 
semiconductor LM358 datasheet, and if it could run on a spilt rail 
instead of a single rail.

As it has V+ /2 going to the + input of the right hand opamp, could 
that be replaced by GND, and all GND signals connected to -V?

Am most interested in using it as a simple voltage controlled TRI wave 
LFO.

Any thoughts anyone?

cheers,
Dave
