GENERAL DESCRIPTION

The ADG858 is a low voltage CMOS device containing four

single-pole, double-throw (SPDT) switches. This device offers

ultralow on resistance of less than 0.82 Ω over the full temperature

range. The ADG858 is fully specified for 4.2 V to 5.5 V and 2.7 V

to 3.6 V supply operation.

Each switch conducts equally well in both directions when on

and has an input signal range that extends to the supplies. The

ADG858 exhibits break-before-make switching action.

The ADG858 is available in a 2.1 mm × 2.1 mm, 16-lead mini

LFCSP. This tiny package makes the part ideal for space-

constrained applications, such as handsets, PDAs, and MP3s.
