GENERAL DESCRIPTION The ADG795A/ADG795G are monolithic CMOS devices comprising five 2:1 multiplexers/demultiplexers controllable via a standard I 2 C serial interface. The CMOS process provides ultralow power dissipation, yet gives high switching speed and low on resistance. The on-resistance profile is very flat over the full analog input range and wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range make the ADG795A/ADG795G the ideal switching solution for a wide range of TV applications including S-video, RGB and YPbPr video switches. The switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG795A/ADG795G switches exhibit break-before-make switching action. The ADG795G has one general-purpose logic output pins controlled by the I 2 C interface that can also be used to control other non-I 2 C-compatible devices such as video filters. The integrated I 2 C interface provides a large degree of flexibility in the system design. It has three configurable I 2 C address pins that allow up to eight devices on the same bus. This allows the user to expand the capability of the device by increasing the size of the switching array.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
