Overview
The ADG451BNZ is a monolithic CMOS device manufactured by Analog Devices Inc., comprising four independently selectable single-pole single-throw (SPST) switches. It is designed on an enhanced LC2MOS process, which provides low power dissipation, high switching speed, and low on-resistance. Each switch conducts equally well in both directions when ON and has an input signal range that extends to the supply rails. This device is ideal for applications requiring low power consumption and high signal integrity.
