How do unused ADC pins need to be connected on the SSM2604? My customer is only using
the DAC and I can't find info on what to do with unused ADC pins (analog in left, right, etc..)
The safest thing to so would be to terminate them to ground through a 10uf cap. You can use one cap. The other option is to terminate them to the VMID pin but that pin is high impedance and anything there will affect the DAC outputs.
