Overview
The ADG431BR-REEL, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable single-pole single-throw (SPST) switches. Fabricated on an enhanced LC2MOS process, this component offers 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 fully to the supply rails. This makes the ADG431BR-REEL suitable for a variety of applications requiring precise signal switching.
