Additional Details

The MAX3271 transimpedance amplifier provides a compact low-power solution for 2.5Gbps communications. It features 495nA input-referred noise, 2GHz bandwidth, and 2mA AC input overload.

The MAX3271 is a compact 30mil x 50mil die and requires no external compensation capacitor. It operates from a single +3.3V supply and consumes 83mW. A space-saving filter connection is provided for positive bias to the photodiode through a 750Ω resistor to V_CC. These features allow easy assembly into a TO-46 or TO-56 header with a photodiode.

The MAX3271 has a typical optical dynamic range of -21dBm to +3dBm in a shortwave configuration or -24dBm to 0dBm in a longwave configuration. The MAX3271 and MAX3272 provide a two-chip solution for Gigabit Ethernet and Fibre Channel receiver applications.
