AD9648-EP Enhanced Product ABSOLUTE MAXIMUM RATINGS Table 6. THERMAL CHARACTERISTICS Parameter Rating
The exposed paddle must be soldered to the ground plane for Electrical the LFCSP package. Soldering the exposed paddle to the printed AVDD to AGND −0.3 V to +2.0 V circuit board (PCB) increases the reliability of the solder joints DRVDD to AGND −0.3 V to +2.0 V and maximizes the thermal capability of the package.

D0A/D0B through D13A/D13B to −0.3 V to DRVDD + 0.2 V AGND Typical θJA is specified for a 4-layer PCB with a solid ground DCOA/DCOB to AGND −0.3 V to DRVDD + 0.2 V plane. As shown Table 7, airflow improves heat dissipation, Environmental which reduces θJA. In addition, metal in direct contact with the Operating Temperature Range −55°C to +125°C package leads from metal traces, through holes, ground, and (Ambient) power planes reduces θJA. Maximum Junction Temperature 150°C
ESD CAUTION
Under Bias Storage Temperature Range −65°C to +150°C (Ambient) Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
