ADE7878 Détails du produit

GENERAL DESCRIPTION
The ADE7854/ADE7858/ADE7868/ADE7878 are high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and three flexible pulse outputs. The ADE78xx devices incorporate second-order sigma-delta (Σ-∆) analog-to-digital converters (ADCs), a digital integrator, reference circuitry, and all of the signal processing required to perform total (fundamental and harmonic) active, reactive (ADE7878, ADE7868, and ADE7858), and apparent energy measurement and rms calculations, as well as fundamental-only active and reactive energy measurement (ADE7878) and rms calculations. A fixed function digital signal processor (DSP) executes this signal processing. The DSP program is stored in the internal ROM memory.

FEATURES
    Highly accurate; supports EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22, and IEC 62053-23 standards
    Compatible with 3-phase, 3- or 4-wire (delta or wye), and other 3-phase services
    Supplies total (fundamental and harmonic) active, reactive (ADE7878, ADE7868, and ADE7858 only), and apparent energy, and fundamental active/reactive energy (ADE7878 only) on each phase and on the overall system
    Less than 0.1% error in active and reactive energy over a dynamic range of 1000 to 1 at TA = 25°C
    Less than 0.2% error in active and reactive energy over a dynamic range of 3000 to 1 at TA = 25°C
    Supports current transformer and di/dt current sensors
    Dedicated ADC channel for neutral current input (ADE7868 and ADE7878 only)
    Less than 0.1% error in voltage and current rms over a dynamic range of 1000 to 1 at TA = 25°C
    Supplies sampled waveform data on all three phases and on neutral current
    Selectable no load threshold levels for total and fundamental active and reactive powers, as well as for apparent powers
    Low power battery mode monitors phase currents for antitampering detection (ADE7868 and ADE7878 only)
    Battery supply input for missing neutral operation Phase angle measurements in both current and voltage channels with a typical 0.3° error
    Wide-supply voltage operation: 2.4 V to 3.7 V
    Reference: 1.2 V (drift +5 ppm/°C typical) with external overdrive capability
    Single 3.3 V supply
    40-lead lead frame chip scale package (LFCSP), Pb-free
    Operating temperature: −40°C to +85°C
    Flexible I2C, SPI, and HSDC serial interfaces

APPLICATIONS
    Energy metering systems
