AD7751ABRS规格书详情
GENERAL DESCRIPTION
The AD7751 is a high-accuracy fault-tolerant electrical energy measurement IC that is intended for use with 2-wire distribution systems. The part specifications surpass the accuracy require ments as quoted in the IEC1036 standard.
FEATURES
High Accuracy, Supports 50 Hz/60 Hz IEC 687/1036
Less than 0.1 Error Over a Dynamic Range of 500 to 1
SuppliesAverage Real Poweron the Frequency Outputs F1 and F2
High-Frequency Output CF Is Intended for Calibration and SuppliesInstantaneous Real Power
Continuous Monitoring of the Phase and Neutral Current Allows Fault Detection in Two-Wire Distribution Systems
AD7751 Uses the Larger of the Two Currents (Phase or Neutral) to Bill—Even During a Fault Condition
Two Logic Outputs (FAULT and REVP) Can be Used to Indicate a Potential Miswiring or Fault Condition
Direct Drive for Electromechanical Counters and Two-Phase Stepper Motors (F1 and F2)
A PGA in the Current Channel Allows the Use of Small Values of Shuntand Burden Resistance
Proprietary ADCs and DSP Provide High Accuracy Over Large Variations in Environmental Conditions and Time
On-Chip Power Supply Monitoring
On-Chip Creep Protection (No Load Threshold)
On-Chip Reference 2.5 V 8 (30 ppm/C Typical) with External Overdrive Capability
Single 5 V Supply, Low Power (15 mW Typical)
Low-Cost CMOS Process
