I don't see the AD8063 listed in the LTspice amplifier menu. What are my options? Is there a similar device I can import?
Thanks,

Hi,
The alternative part for AD8063 is ADA4855-3. You might want to try it instead of ADA4860.
The spice model is available in the product home page in this link.
再说详细一点:
按cn0287设计的电路,数据采集部分完全是按参考板画的,单片机用的是stm32,通过光耦隔离控制.
现在板上元件通讯没有问题,可以读取ad7193的内部温度.
现在正在调试pt100测量部分,ad8063配置能横流电路,输出400uA.外接两线制pt100热电阻.
如果程序里只选通adg738的一路,比如第二路,ad7193内部配置能8倍增益放大,差分信号输入,无极性,则读取通道1的ad值,通过换算基本上和外加电阻值相等.
但是我想轮流切换测量4路pt100的温度值;于是程序里改成每1秒钟执行4路pt100温度采集…
