ADRF6518 (VGA+Adj LPF)- output current=?

Hello,

 

I'm considering using ADRF6518 to drive an ADC whose input common mode is ~0.5V. DC coupled operation is required. Since ADRF6518's minimal output common mode is 0.9V, I'm intending to implement a resistor divider from each of the output pins to GND.

The question is: how much DC current can the ADRF6518 drive into the resistors of the divider without compromising the performance?

 

Thanks,
David.
