Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
DC ELECTRICAL CHARACTERISTICS
(VCC = +3.14V to +5.5V, TA = -40°C to +85°C. Typical values are at VCC = +3.3V, IMOD = 30mA, IBIAS = 60mA, and TA = +25°C,
unless otherwise noted.) (Note 1)

Note 1: Characteristics at -40°C guaranteed by design and characterization. Dice are tested at TA = +25°C only.
Note 2: Tested at RMODSET = 2.49kΩ, RBIASMAX = 1.69kΩ, excluding IBIAS and IMOD.
Note 3: Voltage on BIAS pin is (VCC - 1.6V).
Note 4: Both the bias and modulation currents will be switched off if any of the current set pins are grounded.
Note 5: Accuracy refers to part-to-part variation.
Note 6: Assuming that the laser to monitor-diode transfer function does not change with temperature.
