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
