- 描述 The LT®1462 (dual) and LT1463 (quad) are the first micropower op amps (45µA max per amp) to offer picoampere input bias currents (1pA typ) and unity gain stability for capacitive loads up to 10nF. LT®1462（双路）和LT1463（四）是第一个微功率运算放大器（每安培最大45μA）提供picoampere的输入偏置电流（1pA的典型值）和团结容性负载的增益稳定到10nF的。 The output can swing a 10k load to within 1.5V of either supply, just like op amps that require an order of magnitude more supply current.一个10K的负载输出摆幅可在任一电源1.5V，就像需要一个幅度电源电流的运算放大器。 This unique combination of performance makes the LT1462/LT1463 ideal over a wide range of input and output impedances.这种独特的性能组合使了广泛的输入和输出阻抗LT1462/LT1463理想。 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. LT1462/LT1463，特别强调在设计和测试已被放置在低成本的性能优化的SO-8（双）和14引脚SO封装（四）为±15V和±5V电源。 The input common mode range includes the positive rail.输入共模范围包括积极的轨道。 Slew rate (0.08V/µs min) and gain bandwidth product (125kHz min) are 100% tested.摆率（0.08V/μs分钟）和增益带宽积（125kHz的分钟），100％测试。 A full set of matching specifications is also provided.还提供全套的配套规范
