Overview
The ADG428BRZ is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. This device comprises eight single channels and is designed to switch one of eight inputs to a common output based on 3-bit binary address lines A0, A1, and A2. It features on-chip address and control latches that facilitate microprocessor interfacing, making it suitable for various bus-controlled systems. The ADG428BRZ is particularly useful in applications requiring low on-resistance, low power consumption, and fast switching times.
