The
l denotes the specications which apply over the full operating temperature range. VS = ±15V, 0°C ≤ TA ≤ 70°C, unless otherwise noted.
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: Typical parameters are dened as the 60% yield of parameter
distributions of individual ampliers, i.e., out of 100 LT2179s (or 100
LT2178s) typically 240 op amps (or 120) will be better than the indicated
specication.
Note 3: This parameter is tested on a sample basis only. All noise
parameters are tested with VS = ±2.5V, VO = 0V.
Note 4: This parameter is guaranteed by design and is not tested.
Note 5: Power supply rejection ratio is measured at the minimum supply
voltage. The op amps actually work at 1.7V supply but with a typical offset
skew of –300μV.
Note 6: This parameter is not 100% tested.
Note 7: During testing at –40°C, the 5V power supply turn-on time is less
than 0.5s.
Note 8: The LT2178C/LT2179C 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.
The
l denotes the specications which apply over the full operating
temperature range. VS = 5V, 0V, VCM = 0.1V, VO = 1.4V, –40°C ≤ TA ≤ 85°C for I-grades, unless otherwise noted. (Note 6)
