MAX4651/MAX4652/MAX4653
General Description
The MAX4651/MAX4652/MAX4653 quad analog switches feature 4Ω max on-resistance (RON) when operating
from a single +5V supply. RON is matched between
switches to 0.2Ω (max) and is flat (0.8Ω max) over the
specified signal range. Each switch can handle Rail-toRail® analog signals. Off-leakage current is 0.1nA at
+25°C. These switches are ideal in low-distortion applications and are the preferred solution over mechanical
relays in automated test equipment or applications
where current switching is required. They have low
power requirements, require less board space, and are
more reliable than mechanical relays.
The MAX4651/MAX4652/MAX4653 operate from a single +1.8V to +5.5V supply, making them ideal for use in
battery-powered applications.
