Overview
The ADG621BRMZ is a monolithic, CMOS, single-pole, single-throw (SPST) analog switch produced by Analog Devices Inc. This device is designed to conduct equally well in both directions when on and features two independent switches. It is a normally open switch with low on-resistance and high switching speeds, making it suitable for a variety of applications. The ADG621BRMZ is available in a compact 10-lead MSOP package, ensuring low power dissipation and TTL/CMOS compatibility.
