GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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 Ω terminated shunt legs, whereas 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 and  
general-purpose high frequency switching applications.
