Overview
The ADG609BR is a high-performance analog multiplexer produced by Analog Devices Inc. This monolithic CMOS device comprises four differential channels, allowing it to switch one of four differential inputs to a common differential output based on the 2-bit binary address lines A0 and A1. An additional EN input enables or disables the device, switching all channels OFF when disabled. The ADG609BR is designed on an enhanced LC²MOS process, which ensures low power dissipation, high switching speed, and low on-resistance. Each channel conducts equally well in both directions when ON and blocks signal levels up to the supplies when OFF. The device also features break-before-make switching to prevent momentary shorting during channel switching.
