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 V other conditions above those indicated in the operational DD + 0.3 V Digital Input Voltage to GND –0.3 V to V section of this specification is not implied. Exposure to absolute DD + 0.3 V Digital Output Voltage to GND –0.3 V to V maximum rating conditions for extended periods may affect DD + 0.3 V Reference Input Voltage to GND –0.3 V to V device reliability. DD + 0.3 V Operating Temperature Range –40°C to +120°C

Junction-to-ambient resistance is more useful for air cooled PCB- mounted components. Rev.
