噪声分析是一项艰巨的任务，对许多设计工程师来说是一个陌生的领域。对噪声性能的最大影响来自伴随输入信号的源阻抗匹配。本文探讨的放大器选型对于新手或经验丰富的人来说，有助于设计者对任何给定的源阻抗都可选性能最佳的运算放大器。 advertisement Op Amp Selection Guide for Optimum Noise Performance Design Note 355 Glen Brisebois Introduction RS VR(EQ) VN Linear Technology continues to add to its portfolio of low + IN noise op amps. This is not because the physics of noise has changed, but because low noise specications are ……
