The MAX3864 is a transimpedance preamplifier for applications in SDH/SONET systems operating up to 2.5Gbps. It features 490nA (typ) input-referred noise, 2.0GHz bandwidth, and 2mA input overload.

The MAX3864 operates from a single +3.0V to +5.5V supply. It includes an integrated low-frequency compensation capacitor, as well as a filter connection that provides positive bias through a 750Ω resistor to VCC. These features save external components, simplifying design and assembly into a TO-46 header with a photodiode.

The MAX3864 has a typical optical dynamic range of -24dBm to 0dBm using a PIN photodetector.
