The MAX4659/MAX4660s' power-supply range is from 4.5V to 20V for dual-supply operation and +9V to +40V for single-supply operation. These switches can operate from any combination of supplies, within a 40V V+ to V- range. They conduct equally well in either direction and can handle Rail-to-Rail analog signals. The off-leakage current is only 1nA max at TA = +25C. The MAX4659 is available in 8-pin MAX and SO packages. The MAX4660 is available in thermally enhanced exposed paddle MAX and SO packages.
