Published:2011/5/22 2:04:00 Author:Robert | Keyword: Low-Drift, Constant Current Source | From:SeekIC

The Low-Drift Constant Current Source Circuit Composed Of MIC2951 is shown in the picture below. Its constant current source's output current is: IL=1.23V/R. In this formula, the value of R should not make the MIC2951's output current exceed 150mA. The accuracy of R is required as the principle of 1%.
