GENERAL DESCRIPTION

The parts have on-board CMOS control logic, which eliminates

the need for external control circuitry. The control inputs

are both CMOS and LVTTL compatible. The low power

consumption of these devices makes them ideally suited

for wireless applications and general-purpose high

frequency switching.

The ADG904 and ADG904-R are wideband analog 4:1

multiplexers 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 isolation is high over the dc to 1 GHz frequency range.

PRODUCT HIGHLIGHTS

The ADG904 and ADG904-R switch one of four inputs to a

common output, RFC, as determined by the 3-bit binary

1. −37 dB off isolation @ 1 GHz

2. 1.1 dB insertion loss @ 1 GHz

3. 20-lead TSSOP/LFCSP packages

address lines A0, A1, and

. A Logic 1 on the

pin disables

the device.
