Stresses above those listed under Absolute Maximum Ratings Parameter Rating may cause permanent damage to the device. This is a stress VDD to GND −0.3 V to +7 V rating only; functional operation of the device at these or any Analog Input Voltage to GND −0.3 V to VDD + 0.3 V other conditions above those listed in the operational sections Digital Input Voltage to GND −0.3 V to +7 V of this specification is not implied. Exposure to absolute Digital Output Voltage to GND −0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect Input Current to Any Pin Except Supplies1 ±10 mA device reliability.

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. Rev.
