This hybrid approach solves many of the problems of high speed data link designs by placing a pre-amplifier close to the See Mechanical Dimensions page 8-19 for Mechanical Drawings. photodiode. The level amplification “T” suffix = Threaded ST package. produced by the transimpedance amplifier makes the output signal much less susceptible to interference which is a problem often found at high data rates This component is susceptible to damage from electrostatic discharge (ESD).
