LT1468 - 90MHz、22V/μs、16 位准确度的运算放大器
LT®1468 是一款精准、高速运算放大器，具 16 位准确度，并能在 900ns 的时间里稳定至 150μV (对于 10V 信号)。精准度与 AC 性能的这种独特组合使 LT1468 成为诸如 DAC 电流至电压转换和 ADC 缓冲器等高准确度应用的最佳选择。输入失调电压和反相输入偏置电流的初始准确度和漂移特性专为负输出应用而设。
90MHz 增益带宽在所有频率条件下均确保了高开环增益，旨在降低失真。在诸如 ADC缓冲器等同相应用中，其低失真和 DC 准确度提供了完整的 16 位 AC 和 DC 性能。
相比于其他的精准运算放大器，LT1468 的 22V/μs 转换速率在诸如有源滤波器和仪表放大器等应用中改善了大信号性能。
LT1468 运用的是互补双极型制造工艺。它采用一种节省空间的 3mm x 3mm 无引线封装以及小外形和 DIP 封装。
