Less than 0.2% error rate with dynamic range 8000:1
- Better than Class 0.2 measurement (based on IEC62053) using CT
- Better than 0.2% error using a shunt resistor
- 24-bit dual AFE with integrated PGAs for high accuracy measurements
- Fast calibration solution available
- Low overhead software allows sharing MCU with system responsibilities
- Example design
