This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2See Analog Input section. 3See Voltage Reference Input Section. 4Specification is for the device in free air: 48-Lead LQFP; θJA = 91°C/W, θJC = 30°C/W 5Specification is for the device in free air: 48-Lead LFCSP; θJA = 26°C/W.

Voltage Reference Levels for Timing 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. |
