Two Channel Energy Measurement IC CS5490
The CS5490 is part of the CS548x/9x family of high performance analog front end solutions for energy measurement with two (CS5490), three (CS5480) or four (CS5484) 24-bit analog to digital converters. It provides high-accuracy energy measurement at a very low price, and on-chip energy calculations and fast on-chip calibration speeds product development cycles. Flexibility in current sensors, serial communications and digital outputs ensures that the CS5490 is a fit for any application requiring high-accuracy energy measurement at a very low price. Features Superior analog performance with ultra-low noise level and high SNR Energy measurement accuracy of 0.1% over 4000:1 dynamic range Current RMS measurement accuracy of 0.1% over 1000:1 dynamic range 2 independent 24 bit, 4th order Delta Sigma modulators for voltage and current measurements Configurable digital output for energy pulses, zero crossing or energy direction Supports shunt resistor, CT and Rogowski coil current sensors Overcurrent, voltage sag and voltage swell detection UART serial interface Internal register protection via checksum and write-protection On-chip voltage reference (25 ppm/°C typ.) Single 3.3V power supply Low power consumption: < 13mW 16-pin SOIC package On-chip measurements / calculations: Active, reactive and apparent power RMS voltage and current Power factor and line frequency Instantaneous voltage, current and power
