AD9434Data SheetABSOLUTE MAXIMUM RATINGS Table 5. Stresses above those listed under Absolute Maximum Ratings ParameterRating may cause permanent damage to the device. This is a stress Electrical rating only; functional operation of the device at these or any AVDD to AGND −0.3 V to +2.0 V other conditions above those indicated in the operational DRVDD to DRGND −0.3 V to +2.0 V section of this specification is not implied. Exposure to absolute AGND to DRGND −0.3 V to +0.3 V maximum rating conditions for extended periods may affect AVDD to DRVDD −2.0 V to +2.0 V device reliability. D0+/D0− Through D11+/D11− −0.3 V to DRVDD + 0.2 V THERMAL RESISTANCE to DRGND DCO+, DCO− to DRGND −0.3 V to DRVDD + 0.2 V The exposed paddle must be soldered to the ground plane for OR+, OR− to DRGND −0.3 V to DRVDD + 0.2 V the LFCSP package. Soldering the exposed paddle to the PCB CLK+ to AGND −0.3 V to AVDD + 0.2 V increases the reliability of the solder joints, maximizing the CLK− to AGND −0.3 V to AVDD + 0.2 V thermal capability of the package.

PDWN to AGND −0.3 V to DRVDD + 0.2 V Airflow increases heat dissipation, effectively reducing θJA. In CSB to AGND −0.3 V to DRVDD + 0.2 V addition, metal in direct contact with the package leads from SCLK/DFS to AGND −0.3 V to DRVDD + 0.2 V metal traces, through holes, ground, and power planes reduces Environmental the θJA.
