LM3824 |
Part Number | LM3824 |
Manufacturer | National Semiconductor |
Description | The LM3824 Current Gauge provides easy to use precision current measurement with virtually zero insertion loss (typically 0.003Ω). The LM3824 is used for high-side sensing. A Delta Sigma analog to digital converter is incorporated to precisely measure the current and to provide a current averaging function. Current is averaged over 6 msec time periods in ord. |
