Overview
The ADG709CRUZ from Analog Devices Inc. is a high-performance CMOS analog multiplexer/demultiplexer. This device is designed to switch one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. An additional enable input (EN) allows the device to be enabled or disabled, with all channels switched off when disabled. The ADG709CRUZ is optimized for low distortion and high-speed signal switching, making it suitable for a variety of applications including data acquisition, communication systems, audio and video switching, and medical instrumentation.
