SA2007P - Sames

SA2007P Programmable Single Phase Energy Metering IC with Tamper Detection

The SAMES SA2007P is a single phase bi-directional energy metering integrated circuit. It provides a cost effective solution for energy meters with electro-mechanical displays, such as stepper motors and impulse counters. A precision oscillator, that replaces an external crystal is integrated on chip. Two current sensor inputs allow the measurement of energy.
