Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Package Thermal Resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB. ψ JB uses a 4-layer and θ JA in still air unless otherwise stated. 4. ICC = 48mA for worst-case conditions with IMOD = 90mA, TA = +85°C, VCC = 3.6. 5. Load = 15Ω. 6. Assuming VCC = 3.0V, Laser bandgap voltage = 1V, laser package inductance = 1nH, laser equivalent ser ies resistor = 5Ω, and damping resistor = 10Ω. |
