Overview
The ADG5408BCPZ-REEL7, produced by Analog Devices Inc., is a high-voltage, latch-up proof, 8-channel analog multiplexer. This monolithic CMOS device is designed to switch one of eight inputs to a common output, controlled by 3-bit binary address lines (A0, A1, and A2). It features an enable input (EN) that allows the device to be enabled or disabled, with all channels switching off when EN is disabled. The ADG5408 is suitable for a wide range of applications due to its flat on-resistance profile over the full analog input range, ensuring good linearity and low distortion, particularly in audio and video signal switching.
