Overview
The ADG508FBNZ, produced by Analog Devices Inc., is a CMOS analog multiplexer that offers robust and reliable signal switching capabilities. This device is part of the ADG508F series, which includes the ADG508F and ADG509F models. The ADG508FBNZ specifically comprises eight single channels, allowing it to switch one of eight inputs to a common output based on 3-bit binary address lines A0, A1, and A2. An additional enable (EN) input allows for the device to be enabled or disabled, with all channels switched off when disabled.
