Overview
The ADG601BRMZ, produced by Analog Devices Inc., is a monolithic, CMOS single-pole single-throw (SPST) analog switch. This device is a normally open (NO) switch, making it an ideal replacement for mechanical relays due to its higher reliability, lower power requirements, and compact package size. The ADG601BRMZ is available in an 8-lead MSOP package, making it suitable for a variety of applications where space is a concern.
