Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ORDERING GUIDE Temperature Package Package Model Range Description Option AD7709ARU –40 ∞C to +85∞C TSSOP RU-24 AD7709BRU –40 ∞C to +85∞C TSSOP RU-24 EVAL-AD7709EB Evaluation Board 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 AD7709 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. |
