Overview
The ADG5208FBRUZ is an 8:1 analog multiplexer produced by Analog Devices Inc. This device is part of the ADG5208F series, which features advanced analog switching capabilities. The ADG5208F switches one of eight inputs to a common output, controlled by 3-bit binary address lines (A0, A1, and A2). An enable input (EN) allows the device to be enabled or disabled, with all channels switching off when EN is disabled. This multiplexer is designed for high-performance applications requiring low capacitance, low charge injection, and robust fault protection.
