产品详情
同相放大器配置能够在一个参考于地的电阻器两端产生一个输入控制电压。这将产生一个精准的电流值。该电流必须由外部晶体管吸收,于是从地输出相同大小的电流并供应至一个参考于负电源的负载电路。工具及仿真模型
LTspice
LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.
To launch ready-to-run LTspice demonstration circuits for this part:
Step 1: Download and install LTspice on your computer.
Step 2: Click on the link in the section below to download a demonstration circuit.
Step 3: If LTspice does not automatically open after clicking the link below, you can instead run the simulation by right clicking on the link and selecting “Save Target As.” After saving the file to your computer, start LTspice and open the demonstration circuit by selecting ‘Open’ from the ‘File’ menu.
