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. T his 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. Output currents up to 50 mA with greater than  
90% efficiency are achievable, while 100 mA achieves greater  
than 80% efficiency.  
Voltage Inverter Configuration with Shutdown (ADM8660)  
T he ADM660 is a pin compatible upgrade for the MAX660,  
MAX665, ICL7660 and LT C1046.  
T he ADM660/ADM8660 is available in 8-pin DIP and narrow-  
body SOIC. T he ADM660 is also available in a 16-lead T SSOP  
package.  
A Frequency Control (FC) input pin is used to select either  
25 kHz or 120 kHz charge-pump operation. T his is used to  
optimize capacitor size and quiescent current. With 25 kHz  
selected, a 10 µF external capacitor is suitable, while with  
120 kHz the capacitor may be reduced to 2.2 µF. T he oscillator  
frequency on the ADM660 can also be controlled with an exter-  
nal capacitor connected to the OSC input or by driving this in-  
put with an external clock. In applications where a higher supply  
voltage is desired it is possible to use the ADM660 to double  
the input voltage. With input voltages from 2.5 V to 7 V, output  
voltages from 5 V to 14 V are achievable with up to 100 mA  
output current.

T he ADM8660 features a low power shutdown (SD) pin in-  
stead of the external oscillator (OSC) pin. T his can be used to  
disable the device and reduce the quiescent current to 300 nA.
