• 2.1 mm × 2.1 mm mini LFCSP

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 device ideal for spaceconstrained applications, such as handsets, PDAs, and MP3s.
