The ADG821BRM from Analog Devices Inc.'s Analog Switch/Mux/Demux series revolutionizes signal routing with its integrated fault detection circuitry. This Interface IC automatically reports channel integrity issues while maintaining <100pA leakage at elevated temperatures. Its dual-supply architecture ( 5V to 20V) accommodates industrial process signals without additional level shifting. The ADG821BRM is extensively used in: semiconductor wafer probers, phased-array antenna controllers, electrophysiology lab equipment, and smart factory robotic arms. Its -60dB crosstalk performance at 10MHz makes it indispensable for high-speed data acquisition systems and spectrum analyzer front-ends.
