    產(chǎn)品信息

    ATSENSE-301(H) are multi-channel analog front end devices which integrate seven simultaneously sampled Sigma-Delta A/D converters, a high-precision voltage reference with up to 10 ppm/??C temperature stability (H-versions), a programmable current signal amplification, a temperature sensor and an SPI interface. Designed to support energy measurement applications in combination with the Microchip'sATSAM4C device family that features a dedicated Cortex?-M4 processor and metrology library and a variety of sensors including Shunt, Current Transformer and Rogowski coils, the ATSENSE-301(H) achieve ANSI C12.20-2002 and IEC 62053-22 metering accuracy classes of up to 0.2% over 3000:1 current range.
