ADA4355ABCZ

ADA4355 is a complete, high performance, current input µModule®. For space savings, the ADA4355 includes all the required active and passive components to realize a complete current to bits data acquisition solution, supporting a small form factor, optical modules as well as multi channel systems. The high speed transimpedance amplifier( TIA) of the device supports 10ns pulse widths, allowing high spatial resolution for Time of Flight (ToF) measurements. Additionally, the ADA4355 includes three TIA gain (TZ) settings to maximize dynamic range. An internal, selectable, analogue low-pass filter (LPF) can limit the device bandwidth with a corner frequency of 100MHz to minimize broadband noise while also serving as an antialiasing filter for the 125MSPS ADC. Typical application includes current to voltage conversion, chemical analysers, mass spectroscopy, time of flight, fibre optic sensing, OTDR, optical amplifiers, reconfigurable optical and add and drop multiplexers(ROADM).
