MAX232 voltage supply
Hi There.
I have a battery operated circuit where i need to convert TTL 0-3V to -4V low and +4V high. I was going to use a MAX232, however I'm unsure of the voltage supplies I wire to the MAX to output these voltages. How do I get -4V and +4V on the Vs- and Vs+ terminals? (pins 2 and 6) My circuit power supply is simply a +12V battery so I can't just wire it to the voltage rails.

Any help would be much appreciated.
