ADG839 is a 0.35Ω CMOS 1.65 V to 3.6 V single SPDT switch/2:1 MUX with features such as low on resistance, excellent audio performance, and high current carrying capability.
The ADG839 is a single‑pole, double‑throw (SPDT) analog switch designed for 1.65 V to 3.6 V operation. It offers ultralow on‑resistance (typical 0.35 Ω, max 0.5 Ω) across a wide temperature range and supports high‑current routing up to 300 mA continuous (500 mA peak). The device is supplied in a 6‑lead SC70 package and is suitable for cellular phones, PDAs, MP3 players, and other battery‑powered systems.
Key features include rail‑to‑rail switching, break‑before‑make action, low total harmonic distortion, and automotive temperature rating of –40 °C to +125 °C. Detailed specifications, pin configuration, and typical performance curves are provided in the document.
