ADE9178 Energy Management DSP

Analog Devices ADE9178 Energy Management DSP is a metrology digital signal processor (DSP) for use with a combination of ADE9113/ADE9112/ADE9103 sigma-delta analog-to-digital converters (ADCs). The ADE9178 is a high-accuracy, 3-phase electrical energy measurement IC primarily for the electric vehicle supply equipment (EVSE) market with the serial peripheral interface (SPI) and two flexible pulse outputs. The ADE9178 can interface with up to four daisy-chained ADE9113/ADE9112/ADE9103 devices through SPI protocol. The ADE9178 incorporates all the signal processing required to perform total active energy, apparent energy measurements, and root mean square (RMS) calculations. A fixed function DSP executes this signal processing. The Analog Devices ADE9178 is available in a 40-lead TQFN-EP package.
