12.4 TZA3011B with average loop control
A simplified application using the TZA3011B with average loop control and a DC-coupled
laser at 3.3 V or 5 V laser voltage is illustrated in
to ground for the average loop control. The average power level is determined by the
resistor R
connected to the BIASIN input. The modulation current is determined by the MODIN input
voltage which is generated by the resistor R
MODIN pin.
