Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: If the part is stored outside of the specific operating temperature
range, the output may shift due to hysteresis.
Note 3: ESD (Electrostatic Discharge) sensitive device. Use proper ESD
handling precautions.
Note 4: Output requires 0.1µF for operating current greater than 1mA.
Note 5: This parameter is guaranteed by “reverse breakdown change with
current” test.
Note 6: Peak-to-peak noise is measured with a single highpass filter at
0.1Hz and 2-pole lowpass filter at 10Hz.
Note 7: 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.
Note 8: Temperature coefficient is calculated from the minimum and
maximum output voltage measured at TMIN, Room and TMAX as follows:
TC = (VOMAX – VOMIN)/(TMAX – TMIN)
Incremental slope is also measured at 25°C.
