The MAX3760 is a transimpedance preamplifier for
622Mbps ATM applications. It operates from a single
+5V supply and typically consumes only 100mW
power. The preamplifier converts a small photodiode
current to a differential voltage. A DC cancellation cir-
cuit provides a true differential output swing over a
wide range of input current levels, thus reducing pulse-
width distortion.
6.5kΩ transimpedance gain and 560MHz bandwidth,
combined with low 73nA input-referred noise, provide
-31.5dBm typical sensitivity in 1300nm receivers. The
circuit accepts a 1mAp-p input current, resulting in a
typical optical overload of -3dBm. The device operates
over an extended temperature range of -40°C to +85°C.
The MAX3760 is internally compensated and requires
few external components. In die form it includes a
space-saving filter connection, which provides positive
bias for the photodiode through a 1kΩ resistor to V
These features, combined with the die aspect ratio and
dimensioning, allow the MAX3760 to assemble easily
into a TO-style header with a photodiode.
The MAX3760 is designed to be used with either the
MAX3761 or the MAX3762 limiting-amplifier ICs. When
combined with a photodiode, the chipset forms a com-
plete 5V, 622Mbps receiver. The MAX3760 is available
in die form and in an 8-pin SO package.
