Overview
The ADG5208BCPZ-RL7 is a high-performance, 8-channel analog multiplexer produced by Analog Devices Inc. This device is part of the ADG5208 series, which includes monolithic CMOS analog multiplexers designed for various high-reliability applications. The ADG5208 switches 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 ADG5208BCPZ-RL7 is notable for its ultralow capacitance and charge injection, making it ideal for data acquisition and sample-and-hold applications where low glitch and fast settling times are crucial. Additionally, its fast switching speed and high signal bandwidth make it suitable for video signal switching.
