is the recommended
bypassing capacitor on VSUM.
If board space limits the amount of external circuitry to the
AD8305 it is possible to eliminate the transistor in Figure 34
and connect the resistor divider directly to VSUM. In this case
the bias voltage at VSUM and INPT is set by the resistor values
selected for the divider, not the internal biasing of the AD8305.
