Parameter Rating Supply Voltage 26.4 V Power Dissipation Observed power derating curves Input Voltage (Common Mode) ±VS ± 1 V Differential Input Voltage1 ±0.8 V Differential Input Current ±10 mA Output Short-Circuit Duration Observed power derating curves Storage Temperature Range −65°C to +125°C Operating Temperature Range −40°C to +85°C Lead Temperature (Soldering, 10 sec) 300°C 1 The AD8021 inputs are protected by diodes. Current-limiting resistors are not used to preserve the low noise. If a differential input exceeds ±0.8 V, the input current should be limited to ±10 mA. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; 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. MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the AD8021 is limited by the associated rise in junction tempera- ture. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150°C. Temporarily exceeding this limit can cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175°C for an extended period can result in device failure. While the AD8021 is internally short-circuit protected, this can not be sufficient to guarantee that the maximum junction tem- perature (150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves.

Maximum Power Dissipation vs. Temperature1 1 Specification is for device in free air: 8-lead SOIC: θJA = 125°C/W; 8-lead MSOP: θJA = 145°C/W. ESD 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 this product 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. |
