11 THERMAL CHARACTERISTICS
Notes
1.
2.
Measured in free air as defined by JEDEC standard JESD51-2
These values are given for information only. The thermal resistance depends strongly on the nature and design of
the PCB used in the application.The thermal resistance given corresponds to the value that can be measured on a
multilayer PCB (4 layers) as defined by JEDEC standard.
The junction temperature influences strongly the reliability of an IC. The PCB used in the application contributes in a
large part to the overall thermal characteristic. It must therefore be insured that the junction temperature of the IC
never exceeds T
j(max)
= 150
°
C at the maximum ambient temperature.

; positive currents are entering the IC and negative currents are going out of
the IC; the performances of the circuits are measured in the measurement circuits Figs 27 and 28 for digital application
or in the measurement circuits Figs 29 and 30 for hybrid application; unless otherwise specified.
