Notes: 8. All voltages with respect to AGND.

9. Applies to all pins including continuous over-voltage conditions at the analog input (AIN) pins.

10. Transient current of up to 100 mA will not cause SCR latch-up. Maximum input current for a power

supply pin is ±50 mA.

11. 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.
