Hi,
Most of the opamp based audio filters, I-V converters, differential to
single ended converters, preamps, buffers use +/-12V or +/-15V supply
though the opamp can be operated from as low as +/-5V. Is there any
benifit of using higher volatge power supply for opamps used
particularly in audio related circuits? I have AD797 for DAC output
stage for I-V converter and then for differential to single ended
conversion. What are the disadvantages w.r.t audio quality parameters
like THD+N, Dynamic Range if we operate the opamp at lower volatge
like +/- 6V?
Thanks
