Overview
The ADG409BRZ is a high-performance analog multiplexer designed by Analog Devices Inc. This device is part of the ADG409 series, which features a monolithic CMOS construction using an enhanced LC2MOS process. This process ensures low power dissipation while maintaining high switching speed and low on-resistance. The ADG409BRZ is a dual 4:1 multiplexer, meaning it can switch one of four differential inputs to a common differential output based on 2-bit binary address lines. It also includes an enable input to control the device's operation.
