GENERAL DESCRIPTION
The ADE7762 is a high accuracy polyphase electrical energy
measurement IC. The ADE7762 specifications surpass the
accuracy requirements as quoted in the IEC62053-21 standard.
The only analog circuitry used in the ADE7762 is in the
analog-to-digital converters (ADCs) and reference circuit. All
other signal processing (for example, multiplication, filtering,
and summation) is carried out in the digital domain. This
approach provides superior stability and accuracy over
extremes in environmental conditions and over time.
The ADE7762 supplies average active power information on
the low frequency outputs, F1 and F2. These logic outputs can
be used to directly drive an electromechanical counter or to
interface with a microcontroller (MCU). The CF logic output
gives instantaneous active power information. This output is
intended to be used for calibration purposes.
The ADE7762 includes a power supply monitoring circuit on the
V DD pin. The ADE7762 remains inactive until the supply voltage
on V DD reaches 4 V. If the supply falls below 4 V, the ADE7762
resets and no pulses are issued on F1, F2, and CF.
A multiple multiplexed logic output provides phase dropout per
phase, reverse polarity per phase, and a phase sequence error.
Internal phase matching circuitry ensures that the voltage and
current channels are phase matched. An internal no load
threshold ensures that the ADE7762 does not exhibit any creep
when there is no load.
The ADE7762 is available in a 28-lead SOIC package.
