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.

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.
