Overview
The ADG1234YRUZ-REEL7 is a low capacitance, quad single-pole double-throw (SPDT) analog switch produced by Analog Devices Inc. This device is part of the iCMOS® family, known for its high performance and reliability. The ADG1234 features four independently selectable SPDT switches, each capable of handling ±15 V or +12 V signals. The device is designed to prevent momentary shorting between channels through its break-before-make switching action. An enable (EN) input allows for the device to be easily enabled or disabled, switching all channels off when disabled.
