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