+3.3V, 2.5Gbps Low-Power

Transimpedance Amplifier

General Description

Features

The MAX3271 transimpedance amplifier provides a

compact low-power solution for 2.5Gbps communica-

tions. It features 495nA input-referred noise, 2GHz

bandwidth, and 2mA AC input overload.

ꢀ 2GHz Bandwidth

The MAX3271 is a compact 30mil x 50mil die and

requires no external compensation capacitor. It oper-

ates from a single +3.3V supply and consumes 83mW.

A space-saving filter connection is provided for positive

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 appli-

cations.
