ELECTRICAL CHARACTERISTICS
Note 6:
Excludes load regulation errors.
Note 7:
Peak-to-peak noise is measured with a single highpass filter at
0.1Hz and a 2-pole lowpass filter at 10Hz. The unit is enclosed in a still-air
environment to eliminate thermocouple effects on the leads. The test time
is 10 sec. RMS noise is measured with a single highpass filter at 10Hz and
a 2-pole lowpass filter at 1kHz. The resulting output is full wave rectified
and then integrated for a fixed period, making the final reading an average
as opposed to RMS. A correction factor of 1.1 is used to convert from
average to RMS and a second correction of 0.88 is used to correct for the
nonideal bandpass of the filters.
Note 8:
Long-term stability typically has a logarithmic characteristic and
therefore, changes after 1000 hours tend to be much smaller than before
that time. Total drift in the second thousand hours is normally less than
one third that of the first thousand hours with a continuing trend toward
reduced drift with time. Significant improvement in long-term drift can be
realized by preconditioning the IC with a 100 hour to 200 hour, 125
°
C
burn-in. Long-term stability will also be affected by differential stresses
between the IC and the board material created during board assembly. See
PC Board Layout in the Applications Information section.
Note 9:
Hysteresis in output voltage is created by package stress that
differs depending on whether the IC was previously at a higher or lower
temperature. Output voltage is always measured at 25
°
C, but the IC is
cycled to 85
°
C or –40
°
C before successive measurements. Hysteresis is
roughly proportional to the square of the temperature change. Hysteresis
is not normally a problem for operational temperature excursions where
the instrument might be stored at high or low temperature.
