Overview
The ADG819BRTZ-REEL, produced by Analog Devices Inc., is a monolithic, CMOS, single-pole, double-throw (SPDT) switch. This device is designed on a submicron process, which ensures low power dissipation while providing high switching speed, low on-resistance, and low leakage currents. The ADG819 is ideal for battery-powered and portable instruments due to its low power consumption and operating supply range of 1.8 V to 5.5 V. It is available in several package options, including the 6-lead SOT-23 package, 8-lead MSOP package, and a 6-ball WLCSP package, making it suitable for space-constrained applications.
