ATSENSE-101 is a multi-channel analog front end device which integrates three simultaneously sampled Sigma-Delta A/D converters, a high precision voltage reference with up to 50 ppm/°C temperature stability, a programmable current signal amplification, a temperature sensor and an SPI interface. Designed to support energy measurement applications in combination with the Atmel® ATSAM4C device family that features a dedicated Cortex®-M4 processor and metrology library and a variety of sensors including Shunt, CT and Rogowski coils, the ATSENSE-101 achieve ANSI C12.20-2002 and IEC 62053-22 metering accuracy classes of up to 0.2% over 3000:1 current range.
