The ADG849 is a monolithic, CMOS SPDT switch that operates with a supply range of 1.8V to 5.5V. It features ultralow on-resistance, excellent audio performance, and high current carrying capability.
The ADG849 is a monolithic CMOS single‑pole‑double‑throw (SPDT) switch that operates from 1.8 V to 5.5 V. It offers a typical on‑resistance of 0.5 Ω (0.8 Ω max) and can carry up to 400 mA continuous (600 mA peak) current, making it suitable for low‑distortion audio, video routing, and battery‑powered systems.
The device is supplied in a compact 6‑lead SC70 package and includes break‑before‑make switching, low leakage, and high isolation. Detailed specifications cover on‑resistance flatness, bandwidth (38 MHz ‑3 dB), THD+N (0.01 %), and ESD protection. Pin configuration, ordering information, and typical performance curves are provided for designers.
