While we using the Multiple ADC channels ( in Differential Mode ) on ADuc7060 wheather we need to provide the Bias to all channels or bias is not necessery for ADC working properly.
In case Bias is necessary why it necessary?
The primary and auxiliary ADCs incorporate buffers on their input stages.
This allows to convert signals directly from sensors without the need for external signal conditioning, but requires a minimum input signal of 0.1V.
If using single ended mode, ADC5 should be biased to 0.1V as single-ended channels are selected with respect to ADC5.
(It is possible to bypass the buffer in ADC1CON.)

Even bypassing the buffer with out 0.1v Bias it will not Work properly i.e ADC will not produce the results correctly.
For more help we would need more details on your SW- and HW-configuration.
