Overview
The ADG452BRUZ is a monolithic CMOS device produced by Analog Devices Inc., designed on an enhanced LC2MOS process. This component comprises four independently selectable single-pole single-throw (SPST) switches. It is notable for its low power dissipation, high switching speed, and low on-resistance of 5 Ω. The ADG452BRUZ is suitable for a wide range of applications due to its extended signal range, which fully extends to the supply rails, and its ability to operate with both single and dual power supplies.
