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.
PRODUCT HIGHLIGHTS
1. <0.82 Ω over the full temperature range of −40°C to +85°C.
2. Single 2.3 V to 5.5 V operation.
3. Compatible with 1.8 V CMOS logic.
4. High current handling capability (250 mA continuous
current per channel).
5. Low THD + N: 0.06% typical.
6. 2.1 mm × 2.1 mm, 16-lead mini LFCSP.
