STPMS2 - second-order sigma-delta modulator

Datasheet Summary

Description

The STPMS2 also called “smart sensor” device, is an ASSP designed for effective measurement in power line systems utilizing the Rogowski coil, current transformer and Hall or shunt sensors.

Features

  • VCC supply range 3.2 V to 5.5 V.
  • Two second-order sigma-delta (ΣΔ) modulators.
  • Programmable chopper-stabilized low noise and low offset amplifier.
  • Supports 50-60 Hz, EN 50470-1, EN 50470- 3, IEC 62053-21, IEC 62053-22 and IEC 62053- 23 standard specs for class 1, class 0.5 and class 0.2 AC watt meters.
  • STPMS2L-PUR: less than 0.5% error over 1:5000 range.
  • Precision voltage reference: 1.23 V with programmable TC.
  • Internal low drop regulator @ 3 V (typ. ) Applicat.
