ADG732BCPZ 32-channel analog mux, precision signal switch
The ADG732BCPZ is a high-performance, 32-channel analog multiplexer/demultiplexer from Analog Devices, designed for precision signal routing in industrial automation, test & measurement, and medical imaging systems. This SPI-controlled switch matrix features ultra-low on-resistance (4Ω typical) and flatness (<1Ω), ensuring minimal signal distortion when routing high-speed analog signals up to 200MHz. Operating from ±5V to ±22V dual supplies or +8V to +36V single supply, the ADG732BCPZ supports bipolar analog signals with <0.01% THD, making it ideal for automated test equipment (ATE), data acquisition systems, and ultrasound beamforming applications. Its break-before-make switching prevents channel cross-conduction, while the 1.8V logic-compatible serial interface enables direct control from low-voltage FPGAs and microcontrollers.
The ADG732BCPZ integrates ESD protection up to 2kV (HBM) and features latch-up immunity under all operating conditions, ensuring reliability in electrically harsh environments. Packaged in a space-saving 32-lead LFCSP (5mm×5mm), the device offers channel-to-channel isolation >80dB at 100kHz, critical for high-impedance sensor arrays and multi-parameter monitoring systems. Analog Devices provides SPICE models and PCB layout guidelines to optimize performance in MRI gradient switching, battery cell monitoring, and semiconductor wafer testing.
