• AD8529, about open-loop gain model

    Hello, everyone

    I'm currently designing a non-inverting amplifier circuit with AD8529. Its gain is 2 and it will drive a capacitive load. I want to aquire the open-loop model of AD8529 in order to estimate its transient response and to design appropriate…

  • 咨询AD8529开环增益模型相关问题

    ADI技术专家

    您好。我在使用AD8529设计一个同向放大电路,其后将驱动电容性负载,因此希望获得AD8529的开环增益模型来预计系统瞬态响应性能并添加适当的补偿。测试方法参照《基于运算放大器和模拟集成电路的电路设计》第3版315页图8.5环路增益的测试(取消掉反向输入端寄生电容和负载电容,此时beta=0.5且无零极点),认为T/beta即为开环增益,测试电路和测试结果详见附件文档。具体问题如下:

    1、使用+5V和-5V供电时,可获得与数据手册基本一致的开环增益曲线;使用+12V和0V供电时…
