MAX4648:25 Ohm SPST Analog Switches in SOT23-6

High-Voltage, SPST Analog Switches in Tiny SOT

The MAX4647/MAX4648 are dual-supply single-pole/single-throw (SPST) switches. On-resistance is 25Ω max and flat (2Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 1nA max at +25°C. They conduct analog or digital signals equally well in either direction. The primary application areas are in the switching and routing of signals in telecommunications and test equipment. The MAX4647/MAX4648 are single SPST analog switches. The MAX4647 has one normally closed (NC) switch, and the MAX4648 has one normally open (NO) switch. These devices operate from a single +9V to +36V supply or from dual ±4.5V to ±20V supplies. The MAX4647/MAX4648 are available in tiny 6-pin SOT23 packages.
