Is it possible to use 2 laser drivers in parallel to have the modulation
current of 130 mA?  
Hence it is possible to drive a laser diode which requires a current of 150mA
with two laser diode controllers in parallel: ADN2872?

 

Advised to use two ADN2525 in parallel to deliver max. 130mA modulation current
at high speed.
You can use the BSET and MSET control pins to set the required IBIAS and IMOD
currents. Please note, you have to use AC coupled interface to your laser in
this case.
