is given by:

level, load impedance, temperature and common mode

voltages.

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

using the circuit in Figure 3 with a DC differential input

voltage of 250mV, a differential output voltage of 1V, no

load resistance and an ambient temperature of 85°C, the

supply current (current into Pin 3) measures 50mA. As-

When using higher supply voltages or when driving small

below 150°C.
