ATSENSE Multi-channel Analog Front End Devices

Microchip ATSENSE Multi-channel Analog Front End (AFE) Devices are multichannel devices which integrate three, four, or seven simultaneously sampled Sigma-Delta A/D converters. These converters offer high-precision voltage with up to 10ppm/ºC temperature stability (H-versions), signal amplification, a temperature sensor, and SPI interface. The ATSENSE AFE exceeds ANSI C12.20-2002 and IEC 62053-22 metering accuracy classes of up to 0.2% over 3000:1 current range. These AFE ICs feature single-phase (ATSENSE-101), dual-phase (ATSENSE-201(H)), or poly-phase (ATSENSE-301(H)) energy metering AFE suitable for MCUs and metrology library. The AFE ICs feature three types of acquisition channels such as tamper and temperature channels built around the Sigma-Delta A/D converter, voltage channels, and current channels.
