ADE9000 Technical Reference Manual UG-1098

Rev. 0 | Page 5 of 86

The ADC data in the waveform buffer is stored as 32-bit data by

shifting left by 4 bits and sign extending, as shown in Table 3.

The expected output code in the waveform buffer from the sinc

filter when input is at 1 V peak is 67,107,786 (decimal). The

expected output code in the waveform buffer from the decimator

filter when input is at 1 V peak is 74,518,668. See the Waveform

Buffer section for more information.

VOLTAGE REFERENCE

The ADE9000 supports a 1.25 V internal reference. An external

reference can be connected between the REFIN and REFGND

pins. When using an external voltage reference, set the

EXT_REF bit of the CONFIG1 register, which disables the

internal reference buffer.
