Overview
The ADG451BR-REEL7 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 conducts equally well in both directions when ON and has an input signal range that extends to the supplies. The ADG451BR-REEL7 is known for its low power dissipation, high switching speed, and low on-resistance of 5 Ω.
