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 LT1179s, or 100
LT1178s, 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 = ±2.5, 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 1.7V 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 0.5 seconds.
