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

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

JUNCTION TO BOARD THERMAL IMPEDANCE

The junction to board thermal impedance (θJB) is the thermal

impedance from the die to the leads of the ADL5205. The value

given in Table 4 is based on the standard printed circuit board

(PCB) described in the JESD51-7 standard for thermal testing

of surface-mount components. PCB size and complexity (number

of layers) affect θJB; more layers tend to reduce thermal impedance

slightly.

If the PCB temperature is known, use the junction to board

thermal impedance to calculate the die temperature (also

known as the junction temperature) to ensure that the die

temperature does not exceed the specified limit of 135°C. For

example, if the PCB temperature is 85°C, the die temperature is

given by

TJ = TB + (PDISS × θJB)

The worst case power dissipation for the ADL5205 is 919 mW

(5.25 V × 175 mA, see Table 1). Therefore, TJ is

TJ = 85°C + (0.919 W × 24.4°C/W) = 107.4°C
