Designing Arbitrary Waveform Generator with AD9783

I am trying to construct a circuit that compensates for the gain and offset errors of a 2 channel arbitrary waveform generator.

Currently two LTC1668-50MHz are used to generate + -10v Trangular waveforms (100kHz to 1MHz). Same configuration as the circuit below.

I am trying to implement a waveform generator that can compensate for gain and offset errors using the AD9783.
My question is, how is the best way to connect AUX1P and AUX1N to Output OpAmp?
