Cirrus Logic Energy Measurement ICs

Cirrus Logic Energy Measurement ICs are a high-accuracy energy measurement analog front end. These Energy Measurement ICs incorporate independent 4th order Delta-Sigma analog-to-digital converters for every channel, reference circuitry, and the proven EXL signal processing core to provide active, reactive and apparent energy measurement. RMS and power factor calculations for these Energy Measurement ICs are available and are output via a configurable energy pulse, or direct SPI/UART serial access to on-chip registers. Cirrus Logic Energy Measurement ICs also provide instantaneous current, voltage and power measurements that are available over the serial port.

Features
  • HIGHEST ACCURACY: Very flat over long range; ultra-low noise level; high SNR --makes Cirrus Logic the market leader in accuracy
  • LOW COST: Optimizing die sizes; building devices as hard coded ROMs; no expensive flash memory - allows Cirrus Logic to pass the cost benefits through to customers
  • FAST CALIBRATION: Superior analog performance; offset correction is very fast; calibration time of 2-3 seconds; up to 10 times quicker than many competing SOC solutions - Cirrus Logic can significantly speed production.

  • FLEXIBILITY: Lock in a global metrology portion of the meter's design; free up designers to select the MCU to satisfy local requirements for communications, LCD drive, IO etc. - the Cirrus Logic AFE approach
  • EASE OF USE: Pre-programmed power calculation engine eliminates any need for manual programming and also mitigates security concerns
