The

l denotes the speciﬁcations 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 deﬁned as the 60% yield of parameter

distributions of individual ampliﬁers, i.e., out of 100 LT2179s (or 100

LT2178s) typically 240 op amps (or 120) will be better than the indicated

speciﬁcation.

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 speciﬁcations 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)
