ADE7912/ADE7913

Rev. C | Page 3 of 41

The ADE7912/ADE7913 include isoPower®, an integrated,

isolated dc-to-dc converter. Based on the Analog Devices

Coupler technology, the dc-to-dc converter provides the

regulated power required by the first stage of the ADCs at a

3.3 V input supply. isoPower eliminates the need for an external

dc-to-dc isolation block. The iCoupler chip scale transformer

technology also isolates the logic signals between the first and

second stages of the ADC. The result is a small form factor, total

isolation solution.

The ADE7912/ADE7913 configuration and status registers are

accessed via a bidirectional SPI serial port for easy interfacing

with microcontrollers.

The ADE7912/ADE7913 can be clocked from a crystal or an

external clock signal. To minimize the system bill of materials,

the master ADE7912/ADE7913 can drive the clocks of up to

three additional ADE7912/ADE7913 devices.

Multiple ADE7912/ADE7913 devices can be synchronized to

sample at the same moment and provide coherent outputs.

The ADE7912/ADE7913 are available in a 20-lead, Pb-free,

wide-body SOIC package with 8.3 mm creepage.
