GENERAL DESCRIPTION
The ADG839 is a low voltage CMOS device containing a single-
pole, double-throw (SPDT) switch. This device offers ultralow
on resistance of less than 0.6 Ω over the full temperature range.
The ADG839 is fully specified for 1.8 V, 2.5 V, and 3.3 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
ADG839 exhibits break-before-make switching action.
The ADG839 is available in a 6-lead SC70 package.
