ADM660ARZ

ADM660 is a charge-pump voltage converter. Input voltages ranging from +1.5V to +7V can be inverted into a negative –1.5V to –7V output supply. This inverting scheme is ideal for generating a negative rail in single power supply systems. Only two small external capacitors are needed for the charge pump. The oscillator frequency on the device can also be controlled with an external capacitor connected to the OSC input or by driving this input with an external clock. It is widely used in application such as handheld instruments, portable computers, remote data acquisition, opamp power supplies etc.
