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.
