Overview
The ADG426BRSZ is a high-performance 16-channel analog multiplexer produced by Analog Devices Inc. This device is part of the ADG406, ADG407, and ADG426 family, which are monolithic CMOS analog multiplexers. The ADG426BRSZ specifically switches one of sixteen inputs to a common output, controlled by 4-bit binary address lines (A0, A1, A2, and A3). It features on-chip address and control latches, facilitating easy interfacing with microprocessors. This multiplexer is designed on an enhanced LC2MOS process, offering low power dissipation, high switching speed, and low on-resistance, making it suitable for various high-speed applications.
