LT1167
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be imparied.
Note 2: Does not include the effect of the external gain resistor R
G
.
Note 3: This parameter is not 100% tested.
Note 4: The LT1167AC/LT1167C are designed, characterized and expected
to meet the industrial temperature limits, but are not tested at –40°C and
85°C. I-grade parts are guaranteed.
Note 5: This parameter is measured in a high speed automatic tester that
does not measure the thermal effects with longer time constants. The
magnitude of these thermal effects are dependent on the package used,
heat sinking and air flow conditions.
Note 6: Hysteresis in offset voltage is created by package stress that
differs depending on whether the IC was previously at a higher or lower
temperature. Offset voltage hysteresis is always measured at 25°C, but
the IC is cycled to 85°C I-grade (or 70°C C-grade) or –40°C I-grade
(0°C C-grade) before successive measurement. 60% of the parts will
pass the typical limit on the data sheet.
Note 7: Typical parameters are defined as the 60% of the yield parameter
distribution.
Note 8: Referred to input.
