LTC1049

低功耗的零漂移运算放大器与内部电容

特点

描述

The LTC1049 is a high performance, low power zero-drift operational amplifier.LTC1049是一种高性能，低功耗，零漂移运算放大器。 The two sample-and-hold capacitors usually required externally by other chopper stabilized amplifiers are integrated on the chip.在芯片上集成两个采样和保持，通常需要由其他斩波稳定放大器外部电容器。 Further, the LTC1049 offers superior DC and AC performance with a nominal supply current of only 200µA.此外，LTC1049提供了优越的直流和交流性能与标称电源电流仅为200μA。

The LTC1049 has a typical offset voltage of 2µV, drift of 0.02µV/°C, 0.1Hz to 10Hz input noise voltage of 3µV_PPand typical voltage gain of 160dB.LTC1049具有0.02μV/°C间2μV，漂移，为0.1Hz的典型失调电压至10Hz的输入噪声电压_3μVPP和160分贝典型的电压增益。 The slew rate is 0.8V/µs with a gain bandwidth product of 0.8MHz.摆率与0.8MHz的增益带宽积0.8V/μs。

Overload recovery time from a saturation condition is 6ms, a significant improvement over chopper amplifiers using external capacitors.从饱和条件下的过载恢复时间为6ms，斩波放大器使用外部电容，显着改善。

The LTC1049 is available in a standard 8-pin plastic dual in line, as well as an 8-pin SO package.LTC1049是符合标准的8引脚塑料双，以及8引脚SO封装。 The LTC1049 can be a plug-in replacement for most standard op amps with improved DC performance and substantial power savings.LTC1049可以是一个插件更换改进的DC性能和可观的积蓄力量最标准的运算放大器。
