Overview
The ADG726BSU, produced by Analog Devices Inc., is a versatile 16-channel analog multiplexer designed on an enhanced submicron CMOS process. This device can operate as either a multiplexer or a demultiplexer, making it suitable for a wide range of applications. It features low power dissipation, high switching speed, very low on-resistance, and minimal leakage currents. The ADG726BSU is available in a 48-lead Thin Quad Flatpack (TQFP) package and operates from a single supply of +1.8 V to +5.5 V or a ±2.5 V dual supply.
