For an opAmp rails I need positive and negative voltages i.e. Vcc, Vee.
I’m looking for a good IC which is commonly used for creating split power from a single power supply.
Many recommends ICL7660. And I currently have a MAX232.I know that MAX232 is really not designed to create supply voltages, but can it be used instead? Here’s the details of MAX232: http://www.kynix.com/Detail/581629/MAX232.htm
l need +5V -5V or +9V -9V or +12V -12V all would work.
