Analog Devices ADG849 CMOS SPDT Switch Data Sheet
The ADG849 is a monolithic CMOS single‑pole double‑throw (SPDT) switch designed for low distortion and ultra‑low on‑resistance. It operates from 1.8 V to 5.5 V and is offered in a tiny 6‑lead SC70 package, making it suitable for space‑constrained applications such as cellular phones, PDAs, and audio/video routing.
Key features include a typical on‑resistance of 0.5 Ω, high current capability (400 mA continuous, 600 mA peak), automotive temperature range (‑40 °C to +125 °C), and very low power consumption (<0.01 µW). The sheet provides detailed pin descriptions, absolute maximum ratings, typical performance curves, and test circuit examples.
