GENERAL DESCRIPTION
The ADG918/ADG919 are wideband switches using a
CMOS process to provide high isolation and low insertion
loss to 1GHz. The ADG918 is an absorptive switch
having 50 ohm terminated shunt legs, while the ADG919
is a reflective switch. These devices are designed such that
the isolation is high over the DC to 1GHz frequency
range. They have on board CMOS control logic, thus
eliminating the need for external controlling circuitry.
The control inputs are both CMOS and LVTTL
compatible. The low power consumption of these CMOS
devices makes them ideally suited to wireless applications
and general purpose high frequency switching.

... 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 ADG919 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 ...
