ANALOG DEVICES ADG436 handbook
Datasheet
The ADG436 is a monolithic CMOS device comprising two independently selectable SPDT switches. It is designed on an LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range ensuring good linearity and low distortion when switching audio signals. High switching speed also makes the part suitable for video signal switching.
