GENERAL DESCRIPTION

The ADE7753 features proprietary ADCs and DSP for high

accuracy over large variations in environmental conditions and

time. The ADE7753 incorporates two second-order 16-bit Σ-∆

ADCs, a digital integrator (on CH1), reference circuitry,

temperature sensor, and all the signal processing required to

perform active, reactive, and apparent energy measurements,

line-voltage period measurement, and rms calculation on the

voltage and current. The selectable on-chip digital integrator

provides direct interface to di/dt current sensors such as

Rogowski coils, eliminating the need for an external analog

integrator and resulting in excellent long-term stability and pre-

cise phase matching between the current and voltage channels.

The ADE7753 provides a serial interface to read data, and a

pulse output frequency (CF), which is proportional to the active

power. Various system calibration features, i.e., channel offset

correction, phase calibration, and power calibration, ensure high

accuracy. The part also detects short duration low or high

voltage variations.

The positive-only accumulation mode gives the option to

accumulate energy only when positive power is detected. An

internal no-load threshold ensures that the part does not exhibit

any creep when there is no load. The zero-crossing output (ZX)

produces a pulse that is synchronized to the zero-crossing point

of the line voltage. This signal is used internally in the line cycle

active and apparent energy accumulation modes, which enables

faster calibration.

The interrupt status register indicates the nature of the interrupt,

and the interrupt enable register controls which event produces

an output on the IRQ pin, an open-drain, active low logic output.

The ADE7753 is available in a 20-lead SSOP package.
