This is a stress IN+,1 IN−1 GND − 0.3 V to VDD + 0.3 V rating only; functional operation of the device at these or any or ±130 mA other conditions above those indicated in the operational REF GND − 0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute Supply Voltages maximum rating conditions for extended periods may affect VDD, VIO to GND −0.3 V to +7 V device reliability.
