ADE9153B

The ADE9153B¹is a highly accurate, single-phase, energy metering IC with sensor monitoring and self-calibration. Sensor monitoring with mSure^®technology allows meter health monitoring and advanced tamper detection. The monitoring feature allows the user to check the overall accuracy of the sensor and signal path to identify accuracy drifts that occur over time on the current and voltage channels, independently. Similarly, mSure offers advanced tamper detection with the ability to detect unusual changes on the sensors. mSure runs in parallel to the metering measurements, allowing uninterrupted and unaffected metrology in the ADE9153B. Self-calibration with mSure enables a meter to automatically calibrate the current and voltage channels without accurate reference meters or accurate sources when a shunt resistor is used as the current sensor. The self-calibration feature supports Class 1 and Class 2 meters.The ADE9153B includes three high performance analog-to-digital converters (ADCs), providing an 88 dB signal-to-noise ratio (SNR). The ADE9153B offers accurate measurement of line voltage and current, and calculates active, fundamental reactive, and apparent energy, as well as rms. A wide range of power quality information is included, such as dip and swell detection. Current Channel A is ideal for shunts and has a flexible gain stage providing full-scale input ranges from 62.5 mV peak down to 26.04 mV peak. Current Channel B has gain stages of 1×, 2×, and 4× for use with current transformers (CTs). A high speed, 10 MHz, serial peripheral interface (SPI) port allows access to the ADE9153B registers.¹Protected by U.S. Patents 8,350,558; 8,010,304; WO2013038176 A3; 0113507 A1; 0253102 A1; 0354266 A1; and 0154029 A1.
