GENERAL DESCRIPTIONThe ADG636 is a monolithic device, comprising two independently
selectable CMOS SPDT (Single Pole, Double Throw) switches.
When on, each switch conducts equally well in both directions.
The ADG636 operates from a dual ±2.7 V to ±5.5 V supply, or
from a single supply of +2.7 V to +5.5 V.
This switch offers ultralow charge injection of ±1.5 pC over the
entire signal range and leakage current of 10 pA typical at 25°C.
It offers on-resistance of 85 Ω typ, which is matched to withinΩ between channels. The ADG636 also has low power dissi-
pation yet gives high switching speeds.
The ADG636 exhibits break-before-make switching action and
is available in a 14-lead TSSOP package.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADG636 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.

NOTESStresses 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.Overvoltages at EN, A0, A1, S, or D will be clamped by internal diodes. Current
should be limited to the maximum ratings given.
