GENERAL DESCRIPTION
The ADM660/ADM8660 is a charge-pump voltage converter that can be
used to either invert the input supply voltage giving VOUT = –VIN
or double it (ADM660 only) giving VOUT = 2 VIN.
Input voltages ranging from +1.5 V to +7 V can be inverted into a
negative –1.5 V to –7 V output supply. This inverting scheme is
ideal for generating a negative rail in single power supply
systems.
