MAXIM MAX4675, MAX4676 User Manual

________________General Description

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.

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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
