Product Details

The ADG819 is a monolithic, CMOS SPDT (single pole, double throw) switch. This switch is designed on a submicron process, that provides low power dissipation yet gives high switching speed, low On Resistance and low leakage currents. Low-power consumption and operating supply range of +1.8 V to +5.5 V make the ADG819 ideal for battery-powered, portable instruments.

Each switch of the ADG819 conducts equally well in both directions when on. The ADG819 exhibits break-before- make switching action, thus preventing momentary shorting when switching channels. (See the ADG820 for a switch exhibiting make-before-break action.)

The ADG819 is available in a 6-lead SOT-23 package and an 8-lead µSOIC package as well as a 2×3 array MicroCSP package. This chip occupies only a 2.18mm × 1.14mm area, thus making it the ideal candidate for space-constrained applications.
