摘要：这个可调的电流源提供，包括一个标准的强制检测实验室电源供应器， IC的一个额外的电源供应器，和一个单独的控制电压，控制电压的负载电流（ 1A / V）， 1比1的比例。 Maxim > App Notes > Amplifier and Comparator Circuits General Engineering Topics Keywords: force-sense power supply, high-side current monitor, op amps, control voltage Aug 03, 2010 APPLICATION NOTE 4485 Derive Simple High-Current Source from Lab Supply Abstract:Comprising a standard Force-Sense lab power supply, an additional power supply for the ICs, and a separate control voltage, this adjustable current source provides a 1-to-1 ratio of control voltage to load current (1A/V). A similar version of this article appeared in the October 16, 2008 issue of EDN magazine. When electronic testing requires an adjustable current source, you must often build that piece of test equipment in the lab. You can easily make such a current……
