This application note describes the differences between the ADE7878 and the ADE7880. It discusses the hardware and software differences and provides a header file for the ADE7880.
This document describes the differences between the ADE7878 and ADE7880 integrated circuits, focusing on hardware and software changes. It highlights that the ADE7880 is pin-for-pin compatible with the ADE7878 but includes new antialiasing filters and different register mappings due to increased ADC bandwidth and new harmonic calculations.
The note covers specific functional changes such as the handling of neutral current sensing, the replacement of gain registers, and modifications to threshold registers. It also explains changes in energy accumulation modes, communication verification registers, and checksum calculations. Finally, it provides a method to identify which chip is mounted on a shared evaluation board.
Read Address 0xE618 after power up; a value of 0x0 indicates ADE7878 and 0x2 indicates ADE7880.
No, the ADE7880 computes only the fundamental reactive power/energy, unlike the ADE7878.
