SWITCHES SHOWN FOR A LOGIC “1” INPUT
GENERAL DESCRIPTION
Table I. Truth Table
The ADG601/ADG602 are monolithic CMOS SPST (Single
Pole, Single Throw) switches with On Resistance typically less
than 2.5 Ω. The Low On Resistance flatness makes the ADG601/
ADG602 ideally suited to many applications, particularly those
requiring low distortion. These switches are ideal for replacements for mechanical relays because they are more reliable, have
lower power requirements, and package size is much smaller.
PRODUCT HIGHLIGHTS
The ADG601 is a normally open (NO) switch, while the ADG602
is normally closed (NC). Each switch conducts equally well in
both directions when ON, with the input signal range extending
to the supply rails.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
2
Overvoltages at IN, S, or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADG601/ADG602 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.
