The q denotes specifications which apply over the full operating
temperature range.
Note 1: If the part is stored outside of the specific operating temperature
range, the output may shift due to hysteresis.
Note 2: ESD (Electrostatic Discharge) sensitive device. Use proper ESD
handling precautions.
Note 3: Output requires 0.1µF for operating current greater than 1mA.
Note 4: This parameter is guaranteed by “reverse breakdown change with
current” test.
Note 5: Peak-to-peak noise is measured with a single highpass filter at
0.1Hz and 2-pole lowpass filter at 10Hz.
Note 6: 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.
