GENERAL DESCRIPTION
The ADG801/ADG802 are monolithic CMOS SPST (Single
Pole, Single Throw) switches with On Resistance of less than
0.5 . These switches are designed on an advanced submicron
process that provides extremely low on resistance, high switch-
ing speed and low leakage currents.
The low On Resistance of <0.5 means these parts are ideal
for applications where low on resistance switching is critical.
The ADG801 is a normally open (NO) switch, while the
ADG802 is normally closed (NC). Each switch conducts
equally well in both directions when ON.
The ADG801 and ADG802 are available in 6-lead SOT-23
and 8 Lead SOIC packages.

... 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 ADG801/ADG802 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 ...
