4/8 Channel Fault-Protected Analog Multiplexers
The ADG508F, ADG509F, and ADG528F are CMOS analog multiplexers offering 4‑ or 8‑channel switching with built‑in fault and overvoltage protection. They feature low on‑resistance (≈300 Ω typ), fast switching times, and latch‑up‑proof trench isolation. The devices operate from dual ±15 V supplies and tolerate continuous overvoltage from –40 V to +55 V.
The document provides detailed specifications, truth tables, timing diagrams, absolute maximum ratings, and ordering information for multiple package options (N‑16, R‑16N, R‑16W, N‑18, P‑20A). It also includes typical performance curves, test circuit descriptions, and mechanical outline dimensions.
