Overview
The ADG1209YRUZ-REEL7, produced by Analog Devices Inc., is a low capacitance, 4-channel, ±15 V/+12 V iCMOS analog multiplexer. This device is part of the ADG1209 series, which is designed to switch one of four differential inputs to a common differential output. The switching is controlled by 2-bit binary address lines A0 and A1, and an enable (EN) input allows the device to be enabled or disabled. When disabled, all channels are switched off, and when enabled, each channel conducts equally well in both directions.
