DESCRIPTION

The SAMES SA2002D provides a single chip solution for single phase energy meters. Very few external components are required and it has direct drive capability for electromechanical counters. The SA2002D does not required an external crystal. A precision oscillator, which is supplies the circuitry with a stable frequency, is integrated on chip.
