ADG904BCPZ Wideband 2.5 GHz, 37 dB Isolation at 1 GHz, CMOS 1.65V to 2.75V, 4:1 Mux/SP4T QFN spot stock

Product Descriptions

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.

The ADG904 and ADG904-R switch 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, 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.
