Overview
The ADG725BSUZ, produced by Analog Devices Inc., is a monolithic, CMOS, dual 16-channel analog multiplexer. It features a serially controlled 3-wire interface compatible with SPI®, QSPI™, MICROWIRE™, and some DSP interface standards. This multiplexer can be configured as a dual mux switching one of 16 inputs to one output or as a differential mux switching one of 16 inputs to a differential output. The device 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. It is designed on an enhanced submicron process, ensuring low power dissipation and high switching speed with very low on resistance and leakage currents.
