Overview
The ADG426BRS-REEL, produced by Analog Devices Inc., is a high-performance 16-channel analog multiplexer. This device is part of the ADG406/ADG407/ADG426 family, which are monolithic CMOS analog multiplexers fabricated on an enhanced LC2MOS process. The ADG426 specifically switches one of sixteen inputs to a common output, controlled by 4-bit binary address lines (A0, A1, A2, and A3). It also features on-chip address and control latches, facilitating microprocessor interfacing. The device is known for its low power dissipation, high switching speed, and low on-resistance, making it suitable for various high-speed applications.
