5 / 16 page  LT1057/LT1058 5 10578fc 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 distributions of individual amplifiers; (i.e., out of 100 LT1058s or, 100 LT1057s, typically 240 op amps, or 120 for the LT1057, will be better than the indicated specification). Note 3: This parameter is tested on a sample basis only. The l denotes the specifications which apply over the temperature range of –55°C ≤ TA ≤ 125°C, VS = ±15V, VCM = 0V, unless otherwise noted.

The l denotes specifications which apply over the temperature range of VS = ±15V, VCM = 0V, 0°C ≤ TA ≤ 70°C (LT1057SW, LT1058SW) or –40°C ≤ TA ≤ 85°C (LT1057ISW, LT1058ISW), unless otherwise noted. Note 4: Current noise is calculated from the formula: in = (2qlb)1/2 where q = 1.6 • 10–19 coulomb. The noise of source resistors up to 1G swamps the contribution of current noise. Note 5: This parameter is not 100% tested. Note 6: Gain-bandwidth product is not tested. It is guaranteed by design and by inference from the slew rate measurement. |
