1 Absolute maximum voltage for VIN−, VIN+, VINA−, and VINA+ is 6.0 V or

AVDD3 + 0.3 V, whichever is lower.

2 Absolute maximum voltage on digital inputs is 3.0 V or DVDD + 0.3 V,

whichever is lower.

3 Absolute maximum voltage on VREF input is 6.0 V or AVDD4 + 0.3 V,

whichever is lower.

4 Transient currents of up to 100 mA do not cause SCR latch-up.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those listed in the operational sections

of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
