The DS1267 chips have a bias pin to set a DC voltage on the
substrate so that the pots can handle an AC wave form. You are
supposed to set it at -3 volts for a 3-volt peak-to-peak audio signal.
Does this voltage need any significant current along with it?
Are there any other caveats or gotchas regarding this bias voltage?
I will be using a duel-ended supply for the audio op-amps so
it seems like any two resistors whose ratio could give you -3 volts
should be fine.
Thank you.
