... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM660/ADM8660 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... The ADM660/ADM8660 is a switched capacitor voltage con- verter that can be used to invert the input supply voltage. The ADM660 can also be used in a voltage doubling mode. The voltage conversion task is achieved using a switched capacitor technique using two external charge storage capacitors. An on- board oscillator and switching network transfers charge between the charge storage capacitors ...
