mindspeed technologies ? 1 mindspeed proprietary and confidential mc2007 product bulletin product affected: mc2007 literature affected: mc2007 data sheet - 2/11/2000, mindspeed document # 02007-dsh-001-a 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 in to 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, gr eater resistan ce to input overload is provided by the clamping action of the re gulator ouput, however at currents much higher than 4 mapeak, even the regulator output can be damaged by the resulting overvoltage from the pin diode. 02007-PBD-001-A april 28, 2004
