Overview
The ADG608BR-REEL, produced by Analog Devices Inc., is a high-performance analog multiplexer designed to switch one of eight inputs to a common output. This monolithic CMOS device is controlled by 3-bit binary address lines (A0, A1, and A2) and features an enable input (EN) to turn the device on or off. The ADG608 is fabricated on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance. It supports single (+3 V to +5 V) or dual (±5 V) supply voltages, making it versatile for various applications.
