“Classic” High-Precision Low Side Current Sense

这种配置从根本上说就是一种标准的同相放大器。所使用的运放必须支持较低电压轨上的共模操作,而采用的零漂移型运放 (如图所示) 则提供了超卓的精准度。该电路的输出参考于较低的开尔文 (Kelvin) 接点,在单电源应用中此接点可以是地。对于单电源设计,小信号范围将受限于 VOL。调节的准确度由用户所选电阻器的品质来决定。

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.
