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.
