ADA4351-2 Input capacitance & feedback capacitors

Question

I am considering the ADA4351-2 to convert photo diode currents into voltages. Some of the photodiodes have long cables however which means a large input capacitance (up to 1 nF) to the TIA. 
 To prevent oscillations in our own TIAs I use feedback capacitors. The datasheet makes reference to 'internal compensation' reducing the need for external compensation capacitors but doesn't specify any further. 
 
 What input capacitance (for what gains) can these TIAs handle without compensation? 
 Will adding external compensation capacitors be ok?

Hello Adam, 
 You can check the applications information on page 33 of the datasheet for the compensated and non compensated frequency response of ADA4351-2 for various TIA gains. And yes, external compensation capacitors should be ok to use in addition to the 3pF internal feedback capacitance. Figure 86 on page 28 of the datasheet shows an example of a TIA design with overcompensated frequency response considering total source capacitance (including stray capacitance). 
 Hope this helps. Datasheet link: ADA4351-2 (Rev. 0) (analog.com)
