EVAL-ADN2525: bias applied to the laser

Dear All,

Sorry if my question is too simple - just want to double check my understanding.

I use the evaluation board EVAL-ADN2525 to evaluate a semiconductor laser.

The specification sheet of the board is here https://www.analog.com/media/en/technical-documentation/evaluation-documentation/319560078EVAL_ADN2525_NT_ADN2525_OP.pdf

Figure 4 on page 6 shows the schematic of the board.

As far I understand, the bias applied to the board is Vcc (which is 3.3V) minus voltage measured at TP3. Is that correct?

thank you

pavlo
