5 / 19 page AD6644 –5– REV. 0 ABSOLUTE MAXIMUM RATINGS 1 Parameter Min Max Unit ELECTRICAL AVCC Voltage 0 7 V DVCC Voltage 0 7 V Analog Input Voltage 0 AVCC V Analog Input Current 25 mA Digital Input Voltage 0 AVCC V Digital Output Current 4 mA ENVIRONMENTAL 2 Operating Temperature Range (Ambient) –25 +85 °C Maximum Junction Temperature 150 °C Lead Temperature (Soldering, 10 sec) 300 °C Storage Temperature Range (Ambient) –65 +150 °C NOTES 1Absolute maximum ratings are limiting values to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability. 2Typical thermal impedances (52-terminal LQFP); θ JA = 33 °C/W; θ JC = 11 °C/W. These measurements were taken on a 6 layer board in still air with a solid ground plane. EXPLANATION OF TEST LEVELS Test Level I 100% production tested. II 100% production tested at 25 °C, and guaranteed by design and characterization at temperature extremes. III Sample tested only. IV Parameter is guaranteed by design and characterization testing. V Parameter is a typical value only. ORDERING GUIDE Model Temperature Range Package Description Package Option AD6644AST-40 –25 °C to +85°C (Ambient) 52-Terminal LQFP (Low-Profile Quad Plastic Flatpack) ST-52 AD6644AST-65 –25 °C to +85°C (Ambient) 52-Terminal LQFP (Low-Profile Quad Plastic Flatpack) ST-52 AD6644ST/PCB Evaluation Board with AD6644AST–65 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 AD6644 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recom- mended to avoid performance degradation or loss of functionality. WARNING! ESD SENSITIVE DEVICE |
