ADG904BRU

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 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.

The ADG904/ADG904-R switches one of four inputs to a common output, RFC, as determined by the 3-bit binary address lines A0, A1, and EN. A Logic 1 on the EN pin disables the device.

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.
