[Arm-netbook] goodbye LM13700, hello CM108AH

[luke.leighton]

it is with much sadness and regret that for parts in the flying
squirrel i say goodbye to the LM13700M, a part with a huge and rich
history, having seen its first emergence into the world around 1967
even predating the moon landing.  the reason is simple: the bias for
the diodes is 3x 0.7 volts and on rails of +/-2.5V it's simply not
enough.  i'm seeing silence at low volumes... and then huge clipping.
i simply don't have time to resolve this.

instead unless there's a good reason (e.g. conexant responds to
enquiries) i'm going with the CM108AH and keeping the TDA2822 as a
speaker amplifier.  the reason for choosing the CM108AH: no good
reason other than the datasheet contains an example schematic and
there were no NDAs required to get hold of that datasheet.
