ADG904BRU-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG904BRU-REEL is a wideband analog 4:1 multiplexer manufactured by Analog Devices Inc. It operates on a single 1.65 V to 2.75 V power supply and utilizes CMOS/LVTTL control logic. The device features a –3 dB frequency of 2.5 GHz, with an operating frequency up to 2 GHz. Key electrical characteristics include a maximum insertion loss of 1.5 dB at 1000 MHz and off isolation of 37 dB at 1000 MHz. It is housed in a 20-lead TSSOP package and supports an industrial temperature range from -40°C to +85°C.
