MAX4661：2.5Ω、四路、SPST、CMOS模拟开关

The MAX4661/MAX4662/MAX4663 quad analog switches feature low on-resistance of 2.5Ω max. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 5nA max at TA = +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have lower power requirements, use less board space, and are more reliable than mechanical relays. The MAX4661 has four normally closed (NC) switches, and the MAX4662 has four normally open (NO) switches. The MAX4663 has two NC and two NO switches, and features guaranteed break-before-make switching. These devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies. A separate logic supply pin guarantees TTL/CMOS-logic compatibility when operating across the entire supply voltage range.
