描述
The LTC®1050 is a high performance, low cost zero-drift operational amplifier. LTC®1050是一种高性能，低成本的零漂移运算放大器。 The unique achievement of the LTC1050 is that it integrates on-chip the two sample-and-hold capacitors usually required externally by other chopper amplifiers. LTC1050独特的成就是，它集成了片上的两个采样和保持其他斩波放大器通常需要外部电容器。 Further, the LTC1050 offers better combined overall DC and AC performance than is available from other chopper stabilized amplifiers with or without internal sample-and-hold capacitors.此外，LTC1050提供了更好的结合整体的DC和AC性能比从其他斩波稳定放大器，带或不带内部采样和保持电容器。
The LTC1050 has an offset voltage of 0.5µV, drift of 0.01µV/°C, DC to 10Hz, input noise voltage of 1.6µV PP and a typical voltage gain of 160dB. LTC1050具有一个失调电压0.5μV，漂移0.01μV/℃，DC至10Hz，输入噪声电压，1.6μVPP和一个典型的电压增益160分贝。 The slew rate of 4V/µs and a gain bandwidth product of 2.5MHz are achieved with only 1mA of supply current.只有实现供电电流1毫安的4V/μs和一个2.5MHz的增益带宽积的压摆率。
Overload recovery times from positive and negative saturation conditions are 1.5ms and 3ms respectively, which represents an improvement of about 100 times over chopper amplifiers using external capacitors.从正面和负面的饱和条件下的过载恢复时间是1.5ms的分别为3ms，斩波放大器使用外部电容，它代表一个约100倍的改善。 Pin 5 is an optional external clock input, useful for synchronization purposes. 5脚是一个可选的外部时钟输入，用于同步有用。
The LTC1050 is available in standard 8-pin metal can, plastic and ceramic dual-in-line packages as well as an SO-8 package. LTC1050是提供标准的8引脚金属，塑料和陶瓷双列直插式封装以及SO-8封装。 The LTC1050 can be an improved plug-in replacement for most standard op amps. LTC1050可以改进的插件更换为最标准的运算放大器。
