VBIAS output on AD5940

Hi,

I'm using a few analog input pins on the AD5940 to measure the output of instrumentation amps. I would like to supply a the 1.11 VBIAS reference voltage as an offset to the amps, which require a low output-impedance offset voltage source. Is the VBIAS_CAP or VIBAS0 pin a good place to source this?

Thanks in advance.
