Overview
The ADG819BCBZ-REEL7 is a monolithic, CMOS, single-pole, double-throw (SPDT) switch produced by Analog Devices Inc. This switch is designed on a submicron process, which provides low power dissipation while offering 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 a 6-ball Wafer Level Chip Package (WLCSP), an 8-lead MSOP package, and a 6-lead SOT-23 package, making it suitable for space-constrained applications.
