(1) Stresses above these ratings may cause permanent damage.

Exposure to absolute maximum conditions for extended periods

may degrade device reliability. These are stress ratings only, and

functional operation of the device at these or any other conditions

beyond those specified is not supported.

This integrated circuit can be damaged by ESD. Texas

Instruments recommends that all integrated circuits be

handled with appropriate precautions. Failure to observe

proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to

complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could

cause the device not to meet its published specifications.

DESCRIPTION

2.0VPP Internal Reference

1

Default with internal pull-up.

External Reference

0

Internal reference is powered down. Common mode of external reference should be within

50mV of VCM. VCM is derived from the internal bandgap voltage.
