MAX9700
One solution is the configuration shown in Figure 10b.
The potentiometer is connected between the differential
inputs, and these “see” identical RC paths when the
device powers up. The variable resistive element
appears between the two inputs, meaning the setting
affects both inputs the same way. The potentiometer is
audio taper, as in Figure 10a. This significantly
improves transient performance on power-up or release
from SHDN. A similar approach can be applied when
the MAX9700 is driven differentially and a volume con-
trol is required.
