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 VCC.
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.
