LTC2051 双路零漂移运算放大器
LTC®2051/LTC2052 是双通道/四通道零漂移运算放大器，采用 MS8 和 SO-8/GN16以及 S14 封装。对于空间受限型应用，LTC2051 可提供一种 3mm x 3mm x 0.8mm 双侧引脚细间距无引线封装 (DFN)。它们采用单 2.7V 工作电源，并支持 ±5V 应用。电流消耗为每个运算放大器 750μA。
LTC2051/LTC2052 虽然外形尺寸小巧，但 DC 性能却丝毫不打折扣。典型输入失调电压和失调漂移分别为 0.5μV 和10nV/℃.。利用高于 130dB 的电源抑制比 (PSRR) 和共模抑制比 (CMRR)，对几乎为零的 DC 偏移和漂移提供了支持。
输入共模电压范围从负电源至高达正电源的 1V (典型值) 以内。LTC2051/LTC2052 还具有一个增强型输出级，该输出级能够把低至 2kΩ 的负载驱动至正负两个电源轨。开环增益通常为 140dB。另外，LTC2051/LTC2052 还拥有一个 1.5μVP-P 的 DC 至 10Hz 噪声和一个 3MHz 的增益带宽乘积。
