71M6515H - TERIDIAN Semiconductor

71M6515H Energy Meter

The 71M6515H is a high-accuracy analog front-end (AFE) IC that provides measurements for 3-quadrant 3-phase metering. The combination of a 21-bit sigma-delta A/D converter with a six-input analog front-end, a thermally compensated high-precision reference, and a compute engine results in high accuracy and wide dynamic range.
