Overview
The ADG409BNZ is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. This device is designed to switch one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. An additional EN input allows for enabling or disabling the device, with all channels switched off when disabled. The ADG409BNZ is fabricated on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance. It is an improved replacement for the DG409 analog multiplexer and is suitable for various applications requiring high-performance analog switching.
