Each switch of the AG621, AG622, and AG623 conducts equally well in both directions when on. The AG621/AG622/AG623 contain two independent switches. The AG621 and AG622 differ only in that both switches are normally open and normally closed respectively. In the AG623, witch 1 is normally open and witch 2 is normally closed. The AG623 exhibits break-before-make switching action. The AG621/AG622/AG623 offers low on-resistance of 4 Ω, which is matched to within.25 Ω between channels. These switches also provide low power dissipation yet gives high switching speeds. The AG621, AG622, and AG623 are available in a 1-lead µoic package. PROUCT HIGHLIGHT 1.
