Analog Devices ADG333A Quad SPDT Switch Datasheet
The ADG333A is a monolithic CMOS device comprising four independently selectable SPDT switches. It is designed on an LC-MOS process which provides low power dissipation yet achieves a high switching speed and a 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.
The device features low leakage currents (5 nA max) and low charge injection (10 pC max). It exhibits break-before-make switching action for use in multiplexer applications. The ADG333A is ideally suited for portable, battery powered instruments due to its CMOS construction.
