DESCRIPTION

The SAMES SA2005P provides a single chip active energy metering solution for three phase mechanical counter-based meter designs.

Th SA2005P does not require any external trim-pots or resistor ladders for meter calibration. Calibration and meter configuration information is stored on a small external EEPROM.

FEATURES

+ Direct drive for electro-mechanical counters or stepper motors

+ Calibration and setup stored on external EEPROM - no trim-pots required

+ Flexible programmable features providing ease of implementation for meter manufacturers

+ Per phase energy direction and voltage fail indication

+ Precision oscillator on chip

+ Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters

+ Operates over a wide temperature range

+ Easily adaptable to different signal levels

+ Adaptable to different types of sensors

+ Precision voltage reference on-chip

+ Protected against ESD
