LTC2050 采用 SOT-23 封装的零漂移运算放大器
LTC®2050 和 LTC2050HV 是零漂移运算放大器，采用 5 引脚或 6 引脚 SOT-23 和SO-8 封装。LTC2050 采用 2.7V 至 6V 单工作电源。LTC2050HV 采用 2.7V 至 ±5.5V 工作电源。电流消耗为 800μA，而且，采用 6 引脚 SOT-23 和 SO-8 封装的器件版本提供了断电功能 (低态有效)。
LTC2050 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/ºC。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 失调和漂移提供了支持。
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。LTC2050 还具有一个增强型输出级，该输出级能够把低至 2kΩ 的负载驱动至两个电源轨。开环增益通常为 140dB。另外，LTC2050 还拥有一个 1.5μVP-P DC 至 10Hz 噪声和一个 3MHz 的增益带宽乘积。
