Overview
The ADG426BNZ, produced by Analog Devices Inc., is a monolithic CMOS analog multiplexer. This device is part of the ADG406 and ADG426 series, which are designed to switch one of sixteen inputs to a common output based on 4-bit binary address lines (A0, A1, A2, and A3). The ADG426BNZ features on-chip address and control latches, facilitating easy interfacing with microprocessors. It is built on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance, making it suitable for various high-performance applications.
