Overview
The ADG608TRUZ-REEL7 is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. This device is designed to switch one of eight analog inputs to a common output, controlled by 3-bit binary address lines (A0, A1, and A2) and an enable (EN) input. The ADG608 is fully specified for operation with single +3 V, +5 V, or dual ±5 V power supplies, making it versatile for various applications. It is particularly suited for use in battery-operated instruments, data acquisition systems, communication systems, avionics, and medical instrumentation due to its low power dissipation and high switching speed.
