Energy-Measurement Analog Front Ends Offer High Accuracy and Integration for Single-Phase Smart Meters and Power Monitoring
Microchip announced the completion of its high-accuracy, 1-8 channel, single and poly-phase MCP391X energy-measurement Analog Front End (AFE) family. The new MCP3919 and MCP3912 members integrate three and four channels of 24-bit, delta-sigma Analog-to-Digital Conversion (ADC), respectively, with industry-leading accuracy of 93.5 dB SINAD, -107 dB THD and 112 dB SFDR for precise signal acquisition and higher-performing end products. These are the optimal numbers of channels for single-phase energy meters with neutral monitoring (3-channel); or single-phase, three-wire energy meters (4-channel). The high level of integration on the new AFEs also includes a low-drift voltage reference, programmable gain amplifiers, phase-delay compensation and cycle redundancy check (CRC).
