(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.
ABSOLUTE MAXIMUM RATINGS(1)
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from
performance degradation to complete device failure. Texas
Instruments recommends that all integrated circuits be handled
and stored using appropriate 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 speci-
fications.
