Description
ADG3247BRUZ is an Analog Devices digitally controlled analog switch array. It provides four independent SPST (on/off) analog switches that route or isolate analog signals under digital control. The device is designed for low on-resistance when closed, low leakage when open, and fast switching, making it suitable for signal routing in instrumentation, data acquisition, audio/video paths, and test equipment. It typically operates from a single supply and supports a broad analog input range, enabling rail-to-rail signal paths in many applications. Control inputs are CMOS/TTL-compatible for easy interfacing with microcontrollers, FPGAs, or other digital logic. BRUZ specifies the exact packaging/temperature grade for this part (a compact, surface-mount package in a RoHS-compliant variant). Typical applications include channel selection, multiplexing/demultiplexing, and routing choices in signal paths where multiple signals need to be switched on/off quickly and reliably.
