Overview
The ADG409BR-REEL7, produced by Analog Devices Inc., is a high-performance analog multiplexer designed on an enhanced LC2MOS process. This device is part of the ADG409 series, which features four differential channels. It is capable of switching one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. An additional EN input allows for enabling or disabling the device, with all channels switching off when disabled. The ADG409BR-REEL7 is known for its low power dissipation, high switching speed, and low on-resistance, making it suitable for a variety of applications requiring precise signal routing.
