[sdiy] Single supply use of the SSM2164

[Olivier Gillet]

Hi all,

I am working on a +9V (battery or wallwart) powered gadget using a SSM2164.

In the example given in the "Single supply" section of the datasheet,
the mid-rail is obtained through a resistor network + buffer, but I am
concerned that this might not entirely eliminate voltage variations
that might be present in the +9V rail. Would using a voltage reference
work here? What I would like to understand is if there is any
fundamental difference between a SSM2164 and an op-amp when it comes
to single supply use - anything that would make the recommendations
given for op-amps here
http://www.ieee.li/pdf/essay/single_supply_op_amp_design.pdf
irrelevant.

Thanks!
Olivier
