An article about simple techniques for summing with op amps using both the inverting and non-inverting inputs. An example is given of a YPrPb to RGB transcoder for the Xbox. An approach is presented that allows the design equations for the non-inverting input of a summing op amp to be as trivial as those for the inverting input, so that a single summing op amp can be used without complex design equations.

This application note illustrates the use of the fast Static Column Mode of Intel's new CHMOS Dynamic RAMs in the design of a digital signal acquisition device.
