Overview
The ADG812YRU-REEL7 is a low voltage complementary metal-oxide semiconductor (CMOS) device produced by Analog Devices Inc. This component contains four independently selectable single-pole/single-throw (SPST) switches. The ADG812 is part of a family that includes the ADG811 and ADG813, with the primary difference between the ADG811 and ADG812 being the digital control logic; the ADG812 switches are turned on with a logic high, whereas the ADG811 switches are turned on with a logic low.
