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 LT1079s (or 100
LT1078s) 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 V
S
= ±2.5V, V
O
= 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 –300µV.
Note 6: This parameter is not 100% tested.
