7.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)(1)(2)
MIN MAX UNIT
Input voltage 2.7 5.5 V
LED voltage 2 4 V
Junction temperature, TJ –30 110 °C
Ambient temperature, TA(3) –30 85 °C
(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Recommended Operating Ratings are conditions under which operation of the device is ensured. Recommended Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables.
(2) All voltages are with respect to the potential at the GND pins.
(3) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP = 110°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the device/package in the application (RθJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (RθJA × PD-MAX).
