DESCRIPTION
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.

FEATURES
■ Provides direct interface to mechanical counters
■ Calibration and setup stored on external EEPROM - no trimpots required
■ Monitors both Live and Neutral for tamper detection
■ Flexible programmable features
■ Meets the IEC 521/1036 Specification for Class 1 AC Watt hour meters
■ Total power consumption rating below 50mW
■ Adaptable to different types of sensors
■ Operates over a wide temperature range
■ Precision voltage reference on-chip
■ Precision oscillator on chip
