GENERAL DESCRIPTION
The ADSST-EM-3035 Chipset consists of a fast and accurate
6 channel, 16-bit sigma-delta analog-to-digital converter
ADSST-73360AR (ADC), an efficient digital signal processor
ADSST-2185KST-133 (DSP), and Metering Software. The
ADC and DSP are interfaced together to simultaneously acquire
voltage and current samples on all the three phases and perform
mathematically intensive computations to accurately calculate
the Powers, Energies, Instantaneous Quantities, and Harmonics.
The chipset could be interfaced to any general-purpose micropro-
cessor to develop state of the art polyphase or Tri-vector energy
metering solution in accordance with IEC 1036, IEC 687, or
ANSI C12.1.
All calibrations are done in digital domain and no trimming
potentiometers are required.
