Notes
1. Supply current:
2. Power dissipation:
3. The minimum value of the capacitance on pin MONIN is required to prevent instability.
4. The reference currents can be set by connecting external resistors between V
5. See Section “Accuracy of voltage on inputs: ONE, ZERO, ALARMLO, ALARMHI”.
6. See Section “Automatic laser control”.
7. The specified transconductance is the ratio between the modulation current on pins LA or LAQ and the voltage on
