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 input voltage exceeds the supplies, the input current should
be limited to less than 20mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4: The LT1168AC/LT1168C are guaranteed functional over the
operating temperature range of – 40
°C and 85°C.
Note 5: The LT1168AC/LT1168C are guaranteed to meet specified
performance from 0
°C to 70°C. The LT1168AC/LT1168C are designed,
characterized and expected to meet specified performance from – 40
°C
to 85
°C but are not tested or QA sampled at these temperatures. The
LT1168AI/LT1168I are guaranteed to meet specified performance from
–40
°C to 85°C.
Note 6: Typical parameters are defined as the 60% of the yield parameter
distribution.
Note 7: Does not include the tolerance of the external gain resistor RG.
Note 8: 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 9: This parameter is not 100% tested.
Note 10: 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.
The
● denotes the specifications which apply over the – 40
°C ≤ TA ≤ 85°C
temperature range. VS = ±15V, VCM = 0V, RL = 10k unless otherwise noted. (Note 5)
