Hello,


I have a question to the TEC controller chip.

 

My laser diode output depends on the temperature.

 

So, using the TEC controller chip, i want to maintain the temperature automatically when the laser output is 1W.

 

In other words, the laser diode output of 1W is input to the photodiode and photodiode output is some voltage value.

 

At this time, using this voltage value, then the temperature of the object voltage value and the like to be connected to a reference temperature set pin.

 

If so, whether it is set to maintain the temperature for laser output of 1W?

 

Repeat gritty, When i make the typical application circuit in the ADN8831ACPZ-REEL7 manual, i want to maintain the TEC temperature when the laser output packaged with TEC reaches to 1W.

 

if i can, how?
