Overview
The ADG732BCPZ is a 32-channel analog multiplexer produced by Analog Devices Inc. This monolithic, complementary metal oxide semiconductor (CMOS) device 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. It operates from a single supply of +1.8 V to +5.5 V or a ±2.5 V dual supply, making it versatile for various applications. The device is known for its low power dissipation, high switching speed, very low on-resistance, and minimal leakage currents.
