GENERAL DESCRIPTION
The ADG918/ADG919 are wideband switches using a CMOS
process to provide high isolation and low insertion loss to
1 GHz. The ADG918 is an absorptive (matched) switch having
50 terminated shunt legs, while the ADG919 is a reflective
switch. These devices are designed such that the isolation is
high over the dc to 1 GHz 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.
