Qorvo's TIA56 is a versatile high-speed trans-impedance amplifier designed for the amplification and manipulation of signals with data rates to over 43Gb/s. The TIA56 consists of a fully symmetrical differential input and output buffer and is optimized for 50 ohm line termination.
For applications which require adjustable input bias or compensation of DC input currents (e.g. photodiodes) the TIA56 allows adjusting the bias input current for each input independently. By using the output sensing pins, an offset cancellation loop can be established.
The TIA56 exhibits a fully symmetrical differential output buffer which provides either one differential output signal or two single ended output signals. The output voltage swing is fixed to 600 mVpp differential, or 300 mVpp single ended.
