Parameter Rating VAA to GND 7 V Voltage on Any Digital Input Pin GND − 0.5 V to VAA + 0.5 V Storage Temperature (TS) −65°C to +150°C Junction Temperature (TJ) 150°C Lead Temperature (Soldering, 10 sec) 260°C Analog Outputs to GND1 GND − 0.5 V to VAA 1 Analog output short circuit to any power supply or GND can be of an indefinite duration. 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 sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time. PACKAGE THERMAL PERFORMANCE The 44-MQFP 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. For the MQFP package, the junction-to-ambient (θJA) thermal resistance in still air on a four-layer PCB is 35.5°C/W. The junction-to-case thermal resistance (θJC) is 13.75°C/W. For the TQFP package, θJA in still air on a four-layer PCB is 53.2°C/W. θJC is 11.1°C/W. Junction Temperature = TJ = [VAA (Σ DAC Output Current + ICCT) × θJA] + Ambient Temperature. Table 8. Allowable Operating Conditions for KS and KSU Package Options KS, WBS KSU Conditions 3 V 5 V 3 V 5 V 4 DAC ON Double 75R1 Yes +70°C max +70°C max No 4 DAC ON Low Power2 Yes Yes Yes No 4 DAC ON Buffering3 Yes Yes Yes Yes 3 DAC ON Double 75R Yes Yes Yes No 3 DAC ON Low Power Yes Yes Yes Yes 3 DAC ON Buffering Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes 4 DAC ON Buffering Yes Yes 1 DAC ON Double 75R refers to a condition where the DACs are terminated in a double 75R load and low power mode is disabled. 2 DAC ON Low Power refers to a condition where the DACs are terminated in a double 75R load and low power mode is enabled. 3 DAC ON Buffering refers to a condition where the DAC current is reduced to 5 mA and external buffers are used to drive the video load. 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. |
