3Ω Single SPST Analog Switches
____________________________Features
The MAX4675/MAX4676 single analog switches feature
3Ω (max) on-resistance (RON) and 0.7Ω flatness when
operating from dual ±5V supplies. These switches can
handle Rail-to-Rail® analog signals. Off-leakage current
is 0.1nA at TA = +25°C. The MAX4675/MAX4676 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 are more reliable than mechanical
relays, have low power requirements (<1µA), and are
available in a space-saving 6-pin SOT23 package.
The MAX4675 has a single normally open (NO) switch,
and the MAX4676 has a single normally closed (NC)
switch.

o Rail-to-Rail Signal Handling
The MAX4675/MAX4676 operate from either a single
+2.7V to +5.5V or dual ±2.7V to ±5.5V supplies, making them ideal for use in digital card applications and
single-ended 75Ω systems.
