Overview
The ADG812YRUZ-REEL7 is a low-voltage, complementary metal-oxide semiconductor (CMOS) analog switch produced by Analog Devices Inc. This device features four independently selectable single-pole/single-throw (SPST) switches, making it versatile for various switching applications. The ADG812 is part of the ADG811/ADG812 series, differing from the ADG811 in that its digital control logic is inverted, requiring a logic high to turn on the switches.
