These switches are 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 an operating supply range of 1.8 V to 5.5 V make the ADG819 and ADG820 ideal for battery-powered, portable instruments. Each switch of the ADG819 and the ADG820 conducts equally well in both directions when on. The ADG819 exhibits breakbefore-make switching action, thus preventing momentary shorting when switching channels. The ADG820 exhibits make-beforebreak action. The ADG819 and the ADG820 are available in a 6-lead SOT-23 package and an 8-lead µSOIC package. The ADG819 is also available in a 2 × 3 bump 1.14 mm × 2.18 mm MicroCSP package. This chip occupies only a 1.14 mm × 2.18 mm area, making it the ideal candidate for space-constrained applications. 1. Very low ON resistance, 0.5 Ω typical 2. 1.8 V to 5.5 V single-supply operation 3. High current carrying capability 4. Tiny 6-lead SOT-23 package, 8-lead µSOIC package, and 2 × 3 bump 1.14 mm × 2.18 mm MicroCSP package (ADG819 only) REV. 0 Information furnished by Analog Devices is believed to be accurate and reliable.
