CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact
product reliability and result in failures not covered by warranty.
NOTES:
4. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
5. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless
otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications Unless otherwise indicated, all of the following tables are: VSO = VHI = 5V, RSET = 620,
RFREQ = 4.7k, RLOAD-IOUT1/2 = 8 to GND, RLOAD-BLUE = 10 to VHI, PMAX = 0x3FF,
Reg 1 21 = 88h, Reg x-00 bit6 = 0b, TA = +25°C.

NOTES:
6. Required voltage at the device pins. Allowance must be made for any voltage drop between the power supply and the device.
7. Required voltage also depends on laser diode manufacturer and pickup optical efficiency. Also, see ROUT spec of WDAC.
