I have the following filter after the DAC chip (currently with unbalanced outputs) working very well, but I need now to change the DAC chip. The new source has differential outputs.
Is there a simple way to convert the filter (maintaining identical performances) using differential inputs, instead of unbalanced like now?
Is there any simple formula for the components? (Output should remain RCA unbalanced). Usually differencial opamp circuitry should have mirroring components on both inputs, correct?
I doesn't matter to still use two opamps or add an extra one.
