Data Sheet
32-bit register with four MSBs padded with 0s and sign
extended to 28 bits, which practically means it is transmitted
equal to 0xFFF8000.
When the digital integrator is switched off, the ADE7854 /

As stated in the Current Waveform Gain Registers section, the
serial ports of the ADE7854 / ADE7858 / ADE7868 / ADE7878 work
±0.5 V, the ADC produces its maximum output code value.
Figure 41 shows a full-scale voltage signal being applied to the
differential inputs (VA and VN). The ADC output swings
between ?5,928,256 (0xA58AC0) and +5,928,256 (0x5A7540).
