(Reference LTC DWG # 05-08-1610)
Junction temperature, TJ, is calculated from the ambient
temperature, TA, and power dissipation, PD. The power
dissipation is the product of supply voltage, VS, and
supply current, IS. Therefore, the junction temperature
is given by:
TJ = TA + (PD θJA) = TA + (VS IS θJA)
where the supply current, IS, is a function of signal level,
load impedance, temperature and common mode volt-
ages.
For a given supply voltage, the worst-case power dis-
sipation occurs when the differential input signal is
maximum, the common mode currents are maximum
(see Applications Information regarding common mode
DC currents), the load impedance is small and the ambi-
ent temperature is maximum. To compute the junction
temperature, measure the supply current under these
worst-case conditions, estimate the thermal resistance
from Table 2, then apply the equation for TJ. For example,
using the circuit in Figure 3 with DC differential input volt-
age of 250mV, a differential output voltage of 1V, 1kΩ load
resistance and an ambient temperature of 85°C, the supply
current (current into Pin 3) measures 32.2mA. Assuming
a PC board layout with a 35mm2 copper trace, the
θJA is
100°C/W. The resulting junction temperature is:
TJ = TA + (PD θJA) = 85 + (5 0.0322 100) = 101°C
When using higher supply voltages or when driving small
impedances, more copper may be necessary to keep TJ
below 150°C.
