Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifiers, i.e., out of 100 LT2079s (or 100
LT2078s) 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 1.8V supply but with a typical offset
skew of – 300
V.
Note 6: This parameter is not 100% tested.
Note 7: The LT2078C/LT2079C 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.

ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = ±15V, 0°C ≤ TA ≤ 70°C, unless otherwise noted (Note 7).
