Correct operation of ADA4938-1...

I would like to ask if it is possible to use Cf - capacitors parallel to Rf - resistors in feedback like with AD8138 (Figure 42. Circuit Definitions in datasheet) with this differential amplifier (ADA4938-1)? Will be it stable? I want to use it like a output I/V convertor for DAC.

So for this purpose I need high speed differential amplifier (with voltage feedback), low noise and distortion, G=1, supply voltage +/-5V and high quiescent current (>20mA)...


Thank you...
