PRODUCT HIGHLIGHTS
GENERAL DESCRIPTION
1. Single 1.8 V to 5.5 V operation.
2. High current handling capability (400 mA continuous
current).
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 0.41 Ω
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.
3. 1.8 V logic compatible.
4. Low THD + N (0.01% typical).
5. Tiny 2 mm × 1.5 mm WLCSP, 3 mm × 3 mm 10-lead
LFCSP_WD, and 10-lead MSOP packages.
The ADG884 is available in a 10-ball, 2 mm × 1.5 mm WLCSP
package, a 10-lead LFCSP_WD 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.
