Features

  • High accuracy, supporting the accuracy requirements of the 50Hz/60Hz IEC 62053 standard, with an error of less than 0.1 per cent over a dynamic range of 500:1;
  • The active power average is output in frequency from SSP1880 pins F1 and F2;
  • The active power instantaneous value is output from pin CF at a higher frequency and can be used for meter calibration;
  • FI and F2 can directly drive electromechanical counters and two-phase stepper motors;
  • The use of specialised analogue-to-digital converters (ADCs) and digital signal processing (DSPs) ensures a high degree of accuracy even under conditions of highly variable environment and time;
  • Power monitoring circuitry is provided on-chip;
  • Anti-submarine function (no-load threshold) is included in the chip;
  • An on-chip reference voltage of 2.5V±8% (temperature coefficient typical 30ppm/℃) provides a reference for external circuits;
  • A high stability oscillator with little sensitivity to temperature is included on the chip.
  • +5V single-supply, low-power (15mW typical);
  • Low-cost CMOS process.
  • SOP16 package
