Dear,
I would like to get a summing circuit for adding ac and dc offset.
The interested region of AC is around 1MHz~10Mhz with less than 5V amp.
The DC is around +-10V.
Because the frequency could be changed in operation,
I need a constant gain according to the selected frequency.
In most op-amps, there is a variation depending on the frequency.
Does anyone who know some commercial signal adder or best way to make the adder by myself?
Best,
labmaster.
