MAX3760 19-4765; Rev 1; 11/05 EVAALVUAAILTAIOBNLEKIT 622Mbps, Low-Noise Transimpedance Preamplifier for LAN and WAN Optical Receivers General Description 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 circuit provides a true differential output swing over a wide range of input current levels, thus reducing pulsewidth 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 ...
