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 VS = ±2.5, 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 0.5 seconds.
