ADM8660ARZ-REEL

CMOS开关电容电压转换器 CMOS Switched-Capacitor Voltage Converters

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.
