• 描述

  The LTC™1051/LTC1053 are high performance, low cost dual/quad zero-drift operational amplifiers.此外，LTC™1051/LTC1053是高性能，低成本，双通道/四零漂移运算放大器。 The unique achievement of the LTC1051/LTC1053 is that they integrate on chip the sample-and-hold capacitors usually required externally by other chopper amplifiers. LTC1051/LTC1053的独特成就是，他们在芯片上集成的采样和保持电容器通常需要由其他斩波放大器外部。 Further, the LTC1051/LTC1053 offer better combined overall DC and AC performance than is available from other chopper stabilized amplifiers with or without internal sample/hold capacitors.此外，LTC1051/LTC1053提供更好的结合整体的DC和AC性能比是从其他斩波稳定放大器，带或不带内部采样/保持电容。

  The LTC1051/LTC1053 have an offset voltage of 0.5µV, drift of 0.01µV/°C, DC to 10Hz, input noise voltage typically 1.5µV _PP and typical voltage gain of 140dB. LTC1051/LTC1053具有失调电压0.5μV，漂移0.01μV/℃，DC至10Hz，输入噪声电压通常_1.5μVPP和140分贝典型电压增益。 The slew rate of 4V/µs and gain bandwidth product of 2.5MHz are achieved with only 1mA of supply current per op amp.的4V/μs和2.5MHz的增益带宽积的压摆率只达到每运放电源电流1毫安。

  Overload recover times from positive and negative saturation conditions are 1.5ms and 3ms respectively, about a 100 or more times improvement over chopper amplifiers using external capacitors.超载，从正面和负面的饱和条件下的恢复时间是1.5ms的分别为3ms，约100次或以上，超过斩波放大器使用外部电容改善。

  The LTC1051 is available in an 8-lead standard plastic dual-in-line package as well as a 16-pin SW package. LTC1051是在8引线标准的塑料双列直插式封装以及16引脚SW包。 The LTC1053 is available in a standard 14-pin plastic package and an 18-pin SO. LTC1053是在一个标准的14引脚塑料封装和18引脚SO。 The LTC1051/LTC1053 are plug in replacements for most standard dual/quad op amps with improved performance. LTC1051/LTC1053是插在提高性能的最标准的双通道/四运算放大器的替代品。
