Under high power input conditions with detectors not connected to PINK, high power inputs resulting in
more than 2 mA peak current may result in damage to the TIA. This damage is subtle and may manifest
itself in the following ways:
Reduced bandwidth
Reduced sensitivity
Both reduced bandwidth and reduced sensitivity
In extreme cases, higher power supply current
Determining this damage by measuring the leakage into PINA is difficult at best, since the difference
between a good and damaged part is only a few nano-amperes.
In applications using the internal PINK regulator to supply PIN diode bias, greater resistance to input
overload is provided by the clamping action of the regulator ouput, however at currents much higher than
4 mApeak, even the regulator output can be damaged by the resulting overvoltage from the PIN diode.
