ADN2880 for phase measurement

Question

My application is precise optical phase measurement. 
 I am curious if there would be a phase shift as the output voltage from ADN2880 approaches to or goes over the maximum differential swing which is 260mVp-p. 
 Can you also provide me the estimated values for input current, bandwidth, and transimpedance when the input capacitance is 1.5pF?

Dear Lockinamp, 
 ADN2880 is designed to support telecomm and datacomm applications. It is a quantizer design with limited output so it has limited linear detection range. The recommended photo-diode junction capacitance is 0.5pF. When you use a 1.5pF photo-diode with ADN2880, the expected 3dB-BW could be around 833MHz, given photo-diode uses the same process and photo-diode junction capacitance is the optical receiver BW dominator. The input current range and the transimpedance gain specifications are available in the datasheet. 
 Because of its target applications, we never characterized this TIA amplifier as a linear amplifier. No wonder the datasheet has no such information you are looking for. 
 If you believe this TIA is a good candidate to your applications, please contact our local sales team to get further support. 
 Best Regards,
