Overview
The ADG621BRM, produced by Analog Devices Inc., is a monolithic, CMOS, single-pole, single-throw (SPST) switch. This device conducts equally well in both directions when on and contains two independent switches, both of which are normally open. The ADG621 is designed for low on resistance, low power dissipation, and high switching speeds, making it suitable for a variety of applications.
