ADG508A/ADG509A are CMOS monolithic analog multiplexers with eight channels and dual four channels, respectively. The ADG508A switches one of eight inputs to a common output, depending on the state of A0, A1, and A2 pins. The ADG509A switches two inputs to a common output, depending on the state of A0 and A1 pins.
The ADG508A and ADG509A are CMOS monolithic analog multiplexers offering eight‑channel (ADG508A) or four‑differential‑channel (ADG509A) switching. They support a wide dual‑supply range of 10.8 V to 16.5 V, extended signal range from Vss to Vop, and feature break‑before‑make switching.
Key specifications include low power dissipation (28 mW max), typical leakage of 20 pA, on‑resistance around 280 Ω, and switching times of about 200 ns. The devices are available in multiple packages such as PDIP, SOIC, PLCC, LCC and ceramic variants, and operate from –40 °C to +85 °C (commercial) or –55 °C to +125 °C (industrial).
