ADG784 is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet gives high switching speed and low on resistance. The on-resistance variation is typically less than 0.5 Ω with an input signal ranging from 1.8V to 5.5V.
The ADG784 is a monolithic CMOS device that provides four 2:1 multiplexers/demultiplexers with high‑impedance outputs. It operates from a single 3.3 V or 5 V supply, offers rail‑to‑rail operation, and features low insertion loss, low on‑resistance (typical 2.2 Ω) and very low quiescent current (≈100 nA). The device’s bandwidth exceeds 200 MHz, making it suitable for fast Ethernet, audio and video signal switching.
Typical applications include Ethernet adapters, token‑ring networks, audio/video switching, relay replacement, and other high‑speed signal routing tasks. The ADG784’s break‑before‑make switching, low crosstalk (≈‑75 dB) and good off‑isolation (≈‑65 dB) ensure reliable performance in portable and battery‑powered instruments.
