摘要
本文介绍了低噪声、极小的总谐波失真率、增益可编程运算放大器CS3301 在微弱信号检测系统中的应用。介绍了它的性能指标,对其使用方法、应用电路作了详细论述,并给出了相应的试验波形和使用注意事项。同时,软件仿真确定了偏置电流回路电阻的大小及其对放大电路的影响。
The application of CS3301 in weak signal test system is presented in this paper. CS3301 is a operational amplifier with difference input ,difference output and programmable gain , which has many advantages such as high accuracy , low noise, super low total harmonic distortion. The characteristics, applying method and circuit of CS3001 are introduced, as well as some experiment graphs and application notice. At the same time, the resistance of the bias circuit and influence to the system are confirmed by soft simulation.
