Voltage Reference Levels for Timing 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 In sect put ion. 3See Voltage Reference In sect put ion. 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.
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.
