Overview
The ADG658YRQZ is a low-voltage, CMOS analog multiplexer produced by Analog Devices Inc. This device is part of the ADG658 series, which includes eight single channels. It switches one of eight inputs (S1–S8) to a common output, D, as determined by the 3-bit binary address lines A0, A1, and A2. The ADG658YRQZ is designed on an enhanced process that provides lower power dissipation while maintaining high switching speeds. It can operate as either a multiplexer or a demultiplexer and has an input range that extends to the supplies. The device features break-before-make switching action, preventing momentary shorting when switching channels, and all digital inputs have 0.8 V to 2.4 V logic thresholds, ensuring TTL/CMOS logic compatibility with single +5 V or dual ±5 V supplies.
