GENERAL DESCRIPTION
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.
Our Single Converter Technology® reduces cross talk and cost.
This IC also provides RTC and battery backup for time-of-use (TOU) metering.
