The ADE9153B¹ is a highly accurate, single-phase, energy metering IC with sensor monitoring and autocalibration. 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. Autocalibration 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 autocalibration feature supports Class 1 and Class 2 meters.

The ADE9153B includes three high performance analog-to-digital converters (ADCs), providing an 86 dB signal-to-noise ratio (SNR). The ADE9153B offers accurate measurement of line voltage and current, 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, with 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 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.
