Overview
The ADG732BSU, produced by Analog Devices Inc., is a monolithic, complementary metal oxide semiconductor (CMOS) 32-channel analog multiplexer. This device is part of the ADG726/ADG732 family and is designed to switch one of 32 inputs (S1 to S32) to a common output, D, based on the 5-bit binary address lines A0, A1, A2, A3, and A4. The ADG732 is suitable for a wide range of applications due to its low power dissipation, high switching speed, very low on resistance, and minimal leakage currents.
