LM3812 General Description

The LM3812/LM3813 Current Gauges provide easy to use precision current measurement with virtually zero insertion loss (typically 0.004Ω). The LM3812 is used for high-side sensing and the LM3813 is used for low-side sensing. A Delta Sigma analog to digital converter is incorporated to precisely measu.
