This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 28-Lead PDIP: θ JA = 90 °C/W 20-Lead SOIC Package: θ JA = 150 °C/W ADEL2020 2 + 3 4 7 6 1 5 – 0.1 F 10k +VS 0.1 F –VS Figure 3. Offset Null Configuration MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the ADEL2020 is limited by the associated rise in junction tempera- ture. For the plastic packages, the maximum safe junction temperature is 145 °C. If the maximum is exceeded momen- tarily, proper circuit operation will be restored as soon as the die temperature is reduced. Leaving the device in the over- heated condition for an extended period can result in device burnout. To ensure proper operation, it is important to observe the derating curves in figure 4. While the ADEL2020 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature is not exceeded under all conditions.

Maximum Power Dissipation vs. Temperature CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADEL2020 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
