Overview
The ADG819BRM from Analog Devices Inc. is a monolithic, CMOS, single-pole, double-throw (SPDT) switch. Designed on a submicron process, this switch offers low power dissipation, high switching speed, low on resistance, and low leakage currents. It is particularly suited for battery-powered and portable instruments due to its low power consumption and operating supply range of 1.8 V to 5.5 V. The ADG819BRM is available in various packages, including 6-lead SOT-23, 8-lead MSOP, and 6-ball WLCSP, making it ideal for space-constrained applications.
