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.
