... This unique combination of performance makes the LT1462/LT1463 ideal over a wide range of input and output impedances. In the design and testing of the LT1462/LT1463, particular emphasis has been placed on optimizing performance in the low cost SO-8 (dual) and 14-lead SO package (quad) for 15V and 5V supplies ...

... Note 1: Typical parameters are defined as 60% yield of parameter distributions of individual amplifiers, i.e., out of 100 LT1463s (or 100 LT1462s) typically 240 op amps (or 120) will be better than the indicated specification. Note 2: The LT1462 and LT1463 are designed, characterized and expected to meet these extended temperature limits, but are not tested at – and 85 C ...
