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
