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

θJA is thermal resistance, junction to ambient (°C/W), and θJB is

thermal impedance, junction to board (°C/W).

ADL5367

Junction to Board Thermal Impedance

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

impedance from the die to or near the component lead of the

ADL5367. For the ADL5367, θJB is determined experimentally

to 14.74°C/W with the device mounted on a 4-layer circuit

board with two layers as ground planes in a configuration

similar to the ADL5367-EVALZ evaluation board. Board size

and complexity (number of layers) affect θJB; more layers tend to

reduce the thermal impedance slightly.

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

thermal impedance to calculate die temperature (also known

as junction temperature) to ensure it does not exceed the specified

limit of 150°C. For example if the board temperature is 85°C,

the die temperature is given by the equation

Tj = TB + (PDISS × θJB)

where Tj is the junction temperature.

TB is the board temperature measured at or near the

component lead.

PDISS is the power dissipated from the device.

The typical worst case power dissipation for the ADL5367 is

605 mW (5.5 V × 110 mA). Therefore Tj is

Tj = 85°C + (0.605 W × 14.74°C/W) = 93.91°C
