ADG884 General Description
The ADG884 is a low voltage CMOS device containing two independently selectable single-pole, double-throw (SPDT) switches. This device offers ultralow on resistance of less than 0.4 over the full temperature range, making the part an ideal solution for applications that require minimal distortion through the switch. The ADG884 also has the capability of carrying large amounts of current, typically 600 mA at 5 V operation.
The ADG884 is available in a 10 bump, 2.0 mm * 1.50 mm WLCSP package, a 10-lead LFCSP package, and a 10-lead MSOP package. These tiny packages make the ADG884 the ideal solution for space-constrained applications.
When on, each switch conducts equally well in both directions and has an input signal range that extends to the supplies. The ADG884 exhibits break-before-make switching action.
