*Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 microprocessor 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 of ADSST-EM-3035 are done in digital domain and no trimming potentiometers are required.
