GENERAL DESCRIPTION
The ADG619 and the ADG620 are monolithic, CMOS SPDT
(single pole, double throw) switches. Each switch conducts
equally well in both directions when on.
The ADG619/ADG620 offers low On-Resistance of 4 Ω, which
is matched to within 0.7 Ω between channels. These switches also
provide low power dissipation yet give high switching speeds.The
ADG619 exhibits break-before-make switching action, thus
preventing momentary shorting when switching channels. The
ADG620 exhibits make-before-break action.
The ADG619/ADG620 are available in 8-lead SOT-23 pack-
ages and 8-lead Micro-SOIC packages.
