Overview
The ADG1412YRUZ, produced by Analog Devices Inc., is a quad single-pole/single-throw (SPST) analog switch designed using the iCMOS (industrial CMOS) process. This process combines high voltage CMOS and bipolar technologies, enabling the development of high-performance analog ICs that can operate up to 33 V in a compact footprint. The ADG1412 is part of the ADG1411/ADG1412/ADG1413 family, differing primarily in their digital control logic. The ADG1412 switches are turned on with Logic 1, making it suitable for various high-voltage applications requiring low power consumption and minimal signal distortion.
