These are modulator circuits for modulation of video signals on aVHF/UHFcarrier. The circuits require a 5V power supply and few external components for the negative modulation mode. For positive modulation an external clamp circuit is required.

The circuits can be used as general-purpose modulators without additional external components. The IC isTDA6800.
