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