The ICL7660ACPAZ is a CMOS Voltage Converter. The ICL7660A monolithic CMOS power supply circuits which offer unique performance advantages over previously available devices. The ICL7660 performs supply voltage conversions from positive to negative for an input range of +1.5 to +10.0V resulting in complementary output voltages of -1.5 to -10.0V and the ICL7660A does the same conversions with an input range of +1.5 to +12.0V resulting in complementary output voltages of -1.5 to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660A can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input.
