maximum power dissipation exists, close attention to thermal  
board design is required. The value of θJA may vary, depending on  
PCB material, layout, and environmental conditions. The  
specified values of θJA are based on a 4-layer, 4 in. × 3 in. circuit  
board. See JESD51-7 and JESD51-9 for detailed information on  
the board construction. For additional information, see the  
AN-617 Application Note, Wafer Level Chip Scale Package,

Storage Temperature Range  
Operating Junction Temperature Range  
Soldering Conditions  
ΨJB is the junction-to-board thermal characterization parameter  
with units of °C/W. ΨJB of the package is based on modeling and  
calculation using a 4-layer board. The JESD51-12, Guidelines for  
Reporting and Using Electronic Package Thermal Information,  
states that thermal characterization parameters are not the same  
as thermal resistances. ΨJB measures the component power  
flowing through multiple thermal paths rather than a single  
path as in thermal resistance, θJB. Therefore, ΨJB thermal paths  
include convection from the top of the package as well as  
radiation from the package, factors that make ΨJB more useful  
in real-world applications. Maximum junction temperature (TJ)  
is calculated from the board temperature (TB) and power  
dissipation (PD) using the formula  
Stresses at or above those listed under Absolute Maximum  
Ratings may cause permanent damage to the product. This is a  
stress rating only; functional operation of the product at these  
or any other conditions above those indicated in the operational  
section of this specification is not implied. Operation beyond  
the maximum operating conditions for extended periods may  
affect product reliability.  
THERMAL DATA  
Absolute maximum ratings apply individually only, not in  
combination. The ADM7170 can be damaged when the  
junction temperature limits are exceeded. Monitoring ambient  
temperature does not guarantee that TJ is within the specified  
temperature limits. In applications with high power dissipation  
and poor thermal resistance, the maximum ambient  
temperature may need to be derated.  
TJ = TB + (PD × ΨJB)  
See JESD51-8 and JESD51-12 for more detailed information  
about ΨJB.  
THERMAL RESISTANCE  
θJA, θJC, and ΨJB are specified for the worst-case conditions, that  
is, a device soldered in a circuit board for surface-mount  
packages.  
In applications with moderate power dissipation and low  
printed circuit board (PCB) thermal resistance, the maximum  
ambient temperature can exceed the maximum limit provided  
that the junction temperature is within specification limits. The  
junction temperature (TJ) of the device is dependent on the  
ambient temperature (TA), the power dissipation of the device  
(PD), and the junction-to-ambient thermal resistance of the  
package (θJA).

Maximum junction temperature (TJ) is calculated from the

Junction-to-ambient thermal resistance (θJA) of the package is  
based on modeling and calculation using a 4-layer board. The  
junction-to-ambient thermal resistance is highly dependent on  
the application and board layout. In applications where high
