Overview
The ADG426BRS from Analog Devices Inc. is a high-performance, 16-channel analog multiplexer fabricated on an enhanced LC2MOS process. This device is designed to switch one of sixteen inputs to a common output, controlled by 4-bit binary address lines (A0, A1, A2, and A3). The ADG426BRS features on-chip address and control latches, which facilitate microprocessor interfacing. It is suitable for applications requiring low power dissipation, high switching speed, and low on-resistance.
