3 V/5 V CMOS 0.5 Ω SPDT Switch in SC70
Each switch of the ADG849 conducts equally well in both directions when on. The device exhibits break-before-make switching action, thus preventing momentary shorting when switching channels.
The ADG849 is available in a tiny 6-lead SC70 package, thus making it the ideal candidate for space-constrained applications.
