The ADE9000 AFE is an off-the-shelf solution with embedded power quality algorithms and integrated with high-performance analog-to-digital converters (ADCs) in one single device. This integration simplifies additional complex algorithm programming, reduces cost and component count, and increases time-to-market while still achieving high accuracy and enabling EN61000-4-30 Class S for power quality. The ADE9000 AFE enables designers of power-quality monitoring solutions to measure and analyze pollution in order to prevent disruptions and long-term damage, primarily for three-phase power meters.
The ADE9000 AFE integrates seven high-performance ADCs; a high-end reference; a flexible, digital signal processing core; and proprietary algorithms into a single convenient device. High accuracy is driven by the ADCs and reference, which provide low drift over temperature and the highest accuracy over the widest dynamic range. Pre-programmed, proprietary, power-quality software provides real-time monitoring and harmonic analysis, including magnitude and phase information. This enables timely and cost-saving corrective action when necessary.
For power system-meter designers who do not require the advanced power-quality features of the ADE9000, the ADE9078 energy-metering AFE is available for polyphase utility-grade meter applications.
The ADE9000 analog front-end comes in a 40-lead LFCSP package and is list priced at $6.39 each in 1,000-piece quantities. Samples are available now. Evaluation boards cost $390 each.
The ADE9078 Polyphase Utility Meter, in a 40-lead LFCSP package, is list priced at $5.85 each. Evaluation boards are also available for $390 each.
