Overview
The ADG507AKRUZ is a CMOS monolithic analog multiplexer produced by Analog Devices Inc. This device is part of the ADG507A series, which features dual 8-channel analog multiplexers. The ADG507A switches one of eight differential inputs to a common differential output, controlled by three binary addresses and an enable input. It is designed on an enhanced LC2MOS process, enabling operation over a wide range of supply voltages from 10.8 V to 16.5 V, either in single or dual supply configurations. The device is known for its high switching speeds, low RON, and compatibility with TTL and 5 V CMOS logic digital inputs.
