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

1. –37 dB off isolation @ 1 GHz

The ADG904/ADG904-R switches one of four inputs to a

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

2. 1.1 dB insertion loss @ 1 GHz

3. 20-lead TSSOP packages

address lines A0, A1, and

. A Logic 1 on the

pin disables

the device.
