Overview
The ADG451BRUZ is a monolithic CMOS device produced by Analog Devices Inc., designed on an enhanced LC2MOS process. This component features four independently selectable single-pole single-throw (SPST) switches. Each switch is capable of conducting equally well in both directions when in the ON state and has an input signal range that extends to the supplies. The ADG451BRUZ is known for its low power dissipation, high switching speed, and low on-resistance of 5 Ω.
