Supply Voltage 12.6 V Internal Power Dissipation1 While the AD8042 is internally short-circuit protected, this 8-Lead PDIP (N) 1.3 W may not be sufficient to guarantee that the maximum junction 8-Lead SOIC_N (R) 0.9 W temperature (150°C) is not exceeded under all conditions. To Input Voltage (Common Mode) ±V ensure proper operation, it is necessary to observe the S ± 0.5 V Differential Input Voltage ±3.4 V maximum power derating curves.

ESD CAUTION
AD8042 is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150°C. Exceeding this limit temporarily can cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Rev.
