GENERAL DESCRIPTION
The ADG836L is a low voltage CMOS device containing two
independently selectable single-pole, double-throw (SPDT)
switches. This device offers ultralow on resistance of less than
0.8 Ω over the full temperature range. The ADG836L is fully
specified for 3.3 V, 2.5 V, and 1.8 V supply operation.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. The
ADG836L exhibits break-before-make switching action.
The ADG836L is available in a 10-lead package.

1 Overvoltages at IN, S, or D are clamped by internal diodes. Current should be
limited to the maximum ratings given.
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.

ESD 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 this product 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.
