Very low on-resistance, 0.5 ty pical. The ADG849 is a monolithic, CMOS SPDT (single pole, double 2. Tiny, 6-lead SC70 package. throw) switch that operates with a supply range of 1.8 V to 5.5 V. 3. Low power dissipation. The CMOS construction ensures It is designed to offer ultralow on-resistance values of typically low power dissipation. 0.5 . This design makes the ADG849 an ideal solution for 4. High current carrying capability. applications that require minimal distortion through the switch. 5. Low THD + noise (0.01% typ). The ADG849 also has the capability of carrying large amounts of current, typically 600 mA at 5 V operation. 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, making it the ideal candidate for space-constrained applications.
