Overview
The ADG508AKN is a CMOS 8-channel analog multiplexer produced by Analog Devices Inc. This device is part of the ADG508A series, which is designed on an enhanced LC2MOS process. This process enhances the signal capability, allowing the device to operate over a wide range of supply voltages from 10.8 V to 16.5 V, both in single and dual supply configurations. The ADG508AKN switches one of eight inputs to a common output based on the state of three binary addresses and an enable input, making it suitable for various analog switching applications.
