Connecting AD8436 to AD7793

I intend to connect the AD8436 RMS-DC converter to an AD7793. The differential inputs of the AD7793 require the input signal to be biased.

I would like to ask if there is a proper way to use the internal output buffer of the AD8436 to bias its output to, for example, half supply?

Figure 35 in the AD8436 datasheet shows the internal output buffer. Please see attachment.


Thank you for any advice!
