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. 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
