LM3814 - Fast Current Gauge-IC
The LM3814/LM3815 Current Gauges provide easy to use precision current measurement with virtually zero insertion loss (typically 0.004Ω).
The LM3814 is used for high-side sensing and the LM3815 is used for low-side sensing.
A Delta Sigma analog to digital converter is incorporated to precisely measu
