ICL7660 voltage invertor

The ICL7660 is another one of these very useful little IC’s to have in your collection, The ICL7660 is a monolithic, CMOS switched-capacitor voltage converters that can invert, double, divide, or multiply a positive input voltage. In this example we simply invert the voltage.

The MAX1044 from Maxim performs the same task as well.
