APPLICATIONS INFORMATION
Junction temperature, T
temperature, T
dissipation is the product of supply voltage, V
supply current, I
given by:
where the supply current, I
load impedance, temperature and common mode volt-
ages. For a given supply voltage, the worst-case power
dissipation occurs when the differential input signal is
maximum, the common mode currents are maximum (see
the Applications Information section regarding Common
Mode DC Currents), the load impedance is small and

the ambient temperature is maximum. To compute the
junction temperature, measure the supply current under
these worst-case conditions, use 43°C/W as the package
thermal resistance, then apply the equation for T
