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:
3. _JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
4. 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: T_J = T_C = T_A
Standard Conditions Unless otherwise indicated, all of the following tables are: V_SO = V_HI = 5V, R_SET = 620Ω, R_FREQ = 4.7kΩ,
R_LOAD-IOUT1/2 = 8Ω to GND, R_LOAD-BLUE = 10Ω to V_HI, PMAX = 0x3FF, Reg 1-21 = 88h, Reg x-00 bit6 = 0, T_A = +25°C.
Electrical Specifications Standard conditions apply unless otherwise noted.

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