ATSENSE-101/ATSENSE-201(H)/
ATSENSE-301(H)
Multi-Channel Sigma-Delta Analog Front End
Description
ATSENSE-101/ATSENSE-201(H)/ATSENSE-301(H) are multi-channel analog front end devices which integrate three,
four or seven simultaneously sampled Sigma-Delta A/D converters, a high-precision voltage reference with up to 10
ppm/В°C temperature stability (H-versions), a programmable current signal amplification, a temperature sensor and an
SPI interface. When used in data acquisition and energy measurement applications in combination with the Microchip
ATSAM4C device family that features a dedicated CortexВ®-M4 processor and metrology library and a variety of sensors
including Shunt, CT and Rogowski coils, the ATSENSE-101/ATSENSE-201(H)/ATSENSE-301(H) exceeds ANSI
C12.20-2002 and IEC 62053-22 metering accuracy classes of up to 0.2% over 3000:1 current range. Features Analog Front End
