ADG774BRZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG774BRZ-REEL is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs, manufactured by Analog Devices Inc. It operates from a single 3 V or 5 V supply and features a typical on resistance of 2.2 Ω with a maximum of 89 Ω at 3 V operation. The device provides a –3 dB bandwidth of 240 MHz and exhibits very low distortion of 0.5%. It supports rail-to-rail signal ranges and includes break-before-make switching action to prevent channel shorting. The component is housed in a 16-lead Standard Small Outline Package (SOIC) and functions within an operating temperature range of –40°C to +125°C.
