GND – 0.5 V to VAA NOTES 1Stresses 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 listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Analog output short circuit to any power supply or common can be of an indefinite duration. PACKAGE THERMAL PERFORMANCE The 44-PQFP package used for this device takes advantage of an ADI patented thermal coastline lead frame construction. This maximizes heat transfer into the leads and reduces the package thermal resistance. The junction-to-ambient ( θ JA) thermal resistance in still air on a four-layer PCB is 35.5 °C/W. The junction-to-case thermal resis- tance ( θ JC) is 13.75°C/W. 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 ADV7170/ADV7171 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, pr oper ESD precautions are recommended to avoid performance degradation or loss of functionality.
