Datasheet
The MAX3266 is a transimpedance preamplifier for
1.25Gbps local area network (LAN) fiber optic
receivers. The circuit features 200nA input-referred
noise, 920MHz bandwidth, and 1mA input overload.
The MAX3267 provides a pin-for-pin compatible solu-
tion for communications up to 2.5Gbps. It features
500nA input-referred noise, 1.9GHz bandwidth, and
1mA input overload.
Both devices operate from a +3.0V to +5.5V single sup-
ply and require no compensation capacitor. They also
include a space-saving filter connection that provides
positive bias for the photodiode through a 1.5kΩ resistor
to V
or TO-56 header with a photodiode.
The 1.25Gbps MAX3266 has a typical optical dynamic
range of -24dBm to 0dBm in a shortwave (850nm)
configuration or -27dBm to -3dBm in a longwave
(1300nm) configuration. The 2.5Gbps MAX3267 has a
typical optical dynamic range of -21dBm to 0dBm in a
shortwave configuration or -24dBm to -3dBm in a long-
wave configuration.
