Overview
The ADG904BCPZ-REEL is a wideband analog 4:1 multiplexer produced by Analog Devices Inc. This device utilizes a CMOS process to provide high isolation and low insertion loss up to 1 GHz. The ADG904 is available in two versions: the ADG904, which is an absorptive/matched multiplexer with 50 Ω terminated shunt legs, and the ADG904-R, which is a reflective multiplexer. These multiplexers are designed to switch one of four inputs to a common output based on 3-bit binary address lines A0, A1, and EN. The device features on-board CMOS control logic, making it compatible with both CMOS and LVTTL control inputs, and it operates on a single power supply from 1.65 V to 2.75 V.
