NOTES
1.FOR DIGITAL CONTROL, REPLACE R PSET WITH A DIGITAL POTENTIOMETER FROM ANALOG DEVICES:
ADN2850 10-BIT RESOLUTION, 35 ppm/ C TC, EEPROM; AD5242 8-BIT RESOLUTION, 30 ppm/ C TC.
2.TOTAL CURRENT TO LASER = IBIAS + IBIAS
R1/R2.
3.FOR BEST ACCURACY, SIZE R1 TO HAVE A MAXIMUM VOLTAGE DROP ACROSS IT WITHIN THE HEADROOM
CONSTRAINTS.
4.FOR 250 mA EXTRA IBIAS (450 mA TOTAL) FROM AMP1, USE AD8591 AMPLIFIER. AMP1 IS THE OPERATIONAL AMPLIFIER
SHOWN IN THIS FIGURE.
5.FOR 350 mA EXTRA IBIAS (550 mA TOTAL) FROM AMP1, USE ANALOG DEVICES’ SSM2211 AMPLIFIER. AMP1 IS THE
OPERATIONAL AMPLIFIER SHOWN IN THIS FIGURE.
