Overview
LOW INPUT CURRENT HIGH GAIN SPLIT DARLINGTON OPTOCOUPLERS SINGLE-CHANNEL 6N138 6N139 DESCRIPTION The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector.
The split darlington configuration separating the input photodiode and the first stage gain from the output transistor permits lower output saturation voltage and higher speed operation than possible with conventional darlington phototransistor optocoupler.
In the dual channel devices, HCPL-2730/HCPL2731, an integrated emitter - base resistor provides superior stability over temperature.
The combination of a very low input current of 0.
5 mA and a high current ...
