What is different between ADE7757 and ADE7757A(AD71056), except for the reference input range ?
The ADE7757 specifications surpass the accuracy requirements as quoted in the IEC61036 standard, which is IEC625053-21 for ADE7757A. There are some differences between two chips at typical performance characteristics. Their frequency output transfer function for F1 and F2 are different, and their minimum output frequency for F1, F2 and CF are different. Thank you very much.
