Microchip's Energy-Measurement Analog Front Ends Offer High Accuracy for 3-Phase Smart Meters and Multiple-Load Power Monitoring
Microchip's next-generation family of energy-measurement Analog Front Ends (AFEs) feature industry-leading accuracy. The MCP3913 and MCP3914 integrate six and eight 24-bit, sigma-delta Analog-to-Digital Converters (ADCs), respectively, with 94.5 dB SINAD, -106.5 dB THD and 112 dB SFDR for high-accuracy signal acquisition and higher-performing end products. Microchip also announced two new tools to aid in the development of energy systems using these AFEs. The MCP3913 Evaluation Board (part # ADM00522) and MCP3914 Evaluation Board (part # ADM00523) can each be purchased today for $99.99. The MCP3914’s two extra ADCs enable the monitoring of more sensors with one chip, lowering cost and size. Additionally, the programmable data rate of up to 125 ksps with low-power modes allows designers to scale down for better power consumption or to use higher data rates for advanced signal analysis, such as calculating harmonic content. These AFEs also feature a CRC-16 checksum and register-map lock, for increased robustness. For more info, visit: www.microchip.com/get/TEND
