GENERAL DESCRIPTION
The ADG801 and ADG802 are monolithic CMOS, single-pole,
single throw (SPST) switches with on resistance of less than
0.4 Ω. These switches are designed using an advanced
submicron process that provides extremely low on resistance,
high switching speed, and low leakage currents.
The low on resistance of <0.4 Ω makes these parts ideal for
applications where low on resistance switching is critical.
The ADG801 switch is normally open (NO), while the ADG802
is normally closed (NC). Each switch conducts equally well in
both directions when on.
