and yes, it is very comprehensive, giving bandwidth expected for each
design.

For interest:
Bottom of last page:

  The zero biased photovoltaic amplifier offers a 50 kHz to 60 kHz usable
bandwidth. When the detector is reverse biased to -15 V, the typical
isolation amplifier response increases to 100 kHz to 150 kHz. The phase and
frequency response for the IL300 is presented in Fig. 41. When maximum
system bandwidth is desired, the reverse biased photoconductive amplifier
configuration should be considered.
