ADM8829 Switched-Capacitor Voltage Inverter

The ADM8828/ADM8829 is a charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative *1.5 V to *5.5 V output supply. This inverting scheme is ideal for generating a ne.
