(1) Peak-to-peak noise is measured with a 2-pole high-pass filter at 0.1Hz and a 4-pole low-pass chebyshev filter at 10Hz.
(2) Thermal hysteresis is defined as the change in output voltage after operating the device at 25°C, cycling the device through the specified temperature range, and
returning to 25°C.

(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 implied.

PACKAGE/ORDERING INFORMATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from performance
degradation to complete device failure. Texas Instruments recom-
mends that all integrated circuits be handled and stored using appro-
priate ESD protection methods.
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 published specifications.
