AFE General Purpose 4ADC 24-Bit 3.3V 32-Pin TQFP Tray

ATSENSE-201 is 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/°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 Cortex -M4 processor and metrology library and a variety of sensors including Shunt, CT and Rogowski coils, the ATSENSE-201 exceeds ANSI C12.20-2002 and IEC 62053-22 metering accuracy classes of up to 0.2% over 3000:1 current range.
