Overview
The ADG508FBRNZ-REEL7, produced by Analog Devices Inc., is a CMOS analog multiplexer integrated circuit. This device is part of the ADG508F series, which comprises eight single-channel multiplexers. The ADG508F switches one of eight inputs to a common output, controlled by 3-bit binary address lines A0, A1, and A2. An additional enable input allows the device to be enabled or disabled, with all channels switching off when disabled. This multiplexer is designed to handle a wide range of applications requiring high reliability and precision in signal switching.
