GENERAL DESCRIPTION  
The parts have on-board CMOS control logic, thus eliminating  
the need for external control circuitry. The control inputs are  
both CMOS and LVTTL compatible. The ADG904/ADG904-R’s  
low power consumption makes them ideally suited for wireless  
applications and general-purpose high frequency switching.  
The ADG904/ADG904-R are wideband analog 4:1multiplexers  
that use a CMOS process to provide high isolation and low  
insertion loss to 1 GHz. The ADG904 is an absorptive/matched  
mux with 50 Ω terminated shunt legs; the ADG904-R is a  
reflective mux. These devices are designed such that the isola-  
tion is high over the dc to 1 GHz frequency range.  
PRODUCT HIGHLIGHTS
