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 ratings for extended periods may effect device reliability. ORDERING GUIDE Temperature Package Package Model Range Description Option* AD9762AR –40 °C to +85°C 28-Lead 300 mil SOIC R-28 AD9762ARU –40 °C to +85°C 28-Lead TSSOP RU-28 AD9762-EB Evaluation Board *R = SOIC, RU = TSSOP. THERMAL CHARACTERISTICS Thermal Resistance 28-Lead 300 mil SOIC θ JA = 71.4 °C/W θJC = 23°C/W 28-Lead TSSOP θ JA = 97.9 °C/W θJC = 14.0°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 AD9762 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. (TMIN to TMAX, AVDD = +5 V, DVDD = +5 V, IOUTFS = 20 mA unless otherwise noted) WARNING!
