APPLICATIONS
Figure 1. GENERAL DESCRIPTION The ADG819 is a monolithic, CMOS, single-pole, double-throw (SPDT) 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 an 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. The ADG819 is available in a 6-lead SOT-23 package, an 8-lead MSOP package, and in a 6-ball WLCSP package. This chip occupies only a 1.14 mm × 2.18 mm area, making it the ideal candidate for space-constrained applications. PRODUCT HIGHLIGHTS 1. Ver y 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, 8-lead MSOP, and 6-ball, 1.14 mm × 2.18 mm WLCSP packages. D IN ADG819 SWITCHES SHOWN FOR A LOGIC 1 INPUT 02801-001
