Overview
The ADG5409BRUZ, manufactured by Analog Devices Inc., is a high-voltage, latch-up proof, 4-channel multiplexer. This device is part of the ADG5408/ADG5409 family, which includes monolithic CMOS analog multiplexers. The ADG5409 specifically switches one of four differential inputs to a common differential output, controlled by 2-bit binary address lines, A0 and A1. It features an enable input (EN) that allows the device to be enabled or disabled, with all channels switching off when EN is disabled.
