ADG784 is a low power, high speed, low distortion, high switching speed 16-lead QSOP/SOIC package 2:1 switch device. It is suitable for 100VG-AnyLAN token ring 4Mbps/16Mbps ATM25/155 NIC adapters and hubs, audio and video switching, relay replacement and other applications.
The ADG784 is a monolithic CMOS quad 2:1 multiplexer/demultiplexer offering low insertion loss, low on‑resistance (typ. 2.2 Ω) and a flat resistance profile across the full analog input range. It operates from a single 3 V or 5 V supply, is TTL/CMOS compatible, and provides rail‑to‑rail operation with very low distortion (<1%).
With a bandwidth greater than 200 MHz, low crosstalk (‑70 dB @30 MHz) and good off‑isolation (‑60 dB @10 MHz), the device is suitable for fast Ethernet, audio, video and other high‑speed signal switching applications. The part is offered in a chip‑scale package and includes ESD protection, requiring proper handling precautions.
