Question Passlabs D1 with DC servo ?

Hi folks,

By looking in the PCM63 DAC datasheet and datasheets of many other PCMxxxx DACs from Texas (= Burr Brown today),
I can see TI recomends connecting the current output, Iout, to a virtual zero voltage.

Would it be a good idea to add a (very slow regulating) DC-servo to the D1 I/V circuit, to ensure the potential at Iout to stay at zero volts ???

Please refer to attached draft.

Best regards
SHF

Well, at any rate it "beats" spending bills at a bondage parlor.
