Page 1
... 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 5.5 V and 2 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 ...
