Hi,

    I've just started working on an audio project involving an 16F877 and an
Analog Devices SSM2160 (requiring a  -6V,+6V supply). Any hints on how the
two supply voltages should be generated and routed on the PCB in order to
minimise digital leakage in the audio ? I know this isn't a great idea but
if possible I would be using using a small +5V, +12V laptop computer style
switching supply. How can I best isolate the circuit from the switching
noise ? I'm a programmer kind of guy, not an power-supply engineer so please
forgive my electronics shortcomings... _-.\
