Analog Devices ADG508F/ADG509F Analog Multiplexer Datasheet
The ADG508F and ADG509F are CMOS analog multiplexers offering fault‑protected switching. The ADG508F provides eight single‑ended channels, while the ADG509F provides four differential channels. Both devices use a series n‑channel, p‑channel, n‑channel MOSFET structure to protect the device and signal source during over‑voltage or power‑off conditions.
Key features include low on‑resistance, fast switching, break‑before‑make operation, and latch‑up‑proof trench isolation. The parts are TTL and CMOS compatible and support a wide supply range of ±15 V with over‑voltage protection from –40 V to +55 V.
