DYNAMIC CHARACTERISTICS
RECOMMENDED OPERATING CONDITIONS (AGND, DGND = 0 V; See Note 20.)
Notes: 20. All voltages with respect to ground.
ABSOLUTE MAXIMUM RATINGS (AGND, DGND = 0 V; See Note 20.)
Notes: 21. No pin should go more negative than NBV - 0.3 V.
22. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pins.
23. Transient current of up to 100 mA will not cause SCR latch-up. Maximum input current for a power
supply pin is ±50 mA.
24. Total power dissipation, including all input currents and output currents.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
