LM2902D的放大精度为多少?我想任意采用高精度电阻(精度:万分之五)配置LM2902D的放大倍数,放大倍数误差范围是多少?
有没有其他的推荐?谢谢!

放大精度一方面取决于反馈环路电阻精度及温漂,也取决于运放本身的失调、温漂等参数。你想要实现精密放大可参考以下TI的低温漂精密运算放大器系列:http://www.ti.com/lsds/ti/amplifiers-linear/precision-amplifier-products.page
另外你也可以在放大器论坛版块咨询一下:http://www.deyisupport.com/question_answer/analog/amplifiers/f/52.aspx
