GENERAL DESCRIPTION

The ADG849 is a monolithic, CMOS SPDT (single pole, double throw) switch that operates with a supply range of 1.8 V to 5.5 V. It is designed to offer ultralow on-resistance values of typically 0.5 Ω. This design makes the ADG849 an ideal solution for applications that require minimal distortion through the switch. The ADG849 also has the capability of carrying large amounts of current, typically 600 mA at 5 V operation.
