MAX4649：45Ω、SPDT模拟开关，SOT23-8封装

高压、SPDT模拟开关，采用微型SOT封装

The MAX4649 is a dual-supply, single-pole/double-throw (SPDT) analog switch. On-resistance is 45Ω max and flat (7Ω max) over the specified signal range. The MAX4649 can handle rail-to-rail analog signals, and conducts analog or digital signals equally well in either direction. This switch operates from a single +9V to +36V supply, or from ±4.5V to ±20V dual supplies. The primary application areas are in the switching and routing of signals in telecommunications and test equipment. The MAX4649 features a switch transition time of 130ns max at +25°C, and a guaranteed break-before-make switching time of 5ns. Off-leakage current is only 2nA max at +25°C. The MAX4649 is available in a tiny 8-pin SOT23 package.
