FS7755

General Description

The FS7755 is a high accuracy electrical energy measurement IC. The part specifications surpass the accuracy requirements as quoted in the IEC1036 standard. The only analog circuitry used in the FS6611 is in the ADCs and reference circuit. All other signal processing is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.
