Overview
The ADG609BRU is a high-performance analog multiplexer produced by Analog Devices Inc. This component is designed to switch one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. It features an enable input (EN) that allows the device to be enabled or disabled, with all channels switching off when disabled. The ADG609BRU is part of the ADG609 series, which is known for its low power dissipation, high switching speed, and low on-resistance, making it suitable for various applications including data acquisition systems, process controls, avionics, and automatic test equipment (ATEs).
