CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1.
θ
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.
2. All voltages are relative to GND, unless otherwise specified.
3. 1V (min) on the BIAS pin required for FLT to be valid.
4. For
θ
JC
, the “case temp” location is the center of the exposed metal pad on the package underside.
