ADI ADE9322BACPZ Highly Accurate 2-Channel Σ-Δ Analog-To-Digital Converters

Product Overviews
ADE9322BACPZ has highly accurate, 2-channel Σ-Δ analog-to-digital converters (ADCs) with mSure® that converts two analog input signals into a single bit stream output. The device is enabled with an mSure sensor monitoring feature that 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.

Features
mSure sensor monitoring
Noninvasive, real-time direct, precision measurement of the input signal path
Identifies sensor malfunction
Companion microcontroller unit firmware to facilitate diagnostic data reporting
Supported for current shunts and potential divider
mSure self calibration
Automatic calibration based on a direct measurement of the full signal path
Allows calibration up to 0.25% error for each channel
2 high performance Σ-Δ ADCs
Pseudo differential input voltage range: ±41.67 mV peak, +29.46 mV rms input on the current channel
Bit stream output
Industrial temperature range: −40°C to +85°C
Integrated temperature sensor with a 12-bit successive approximation register (SAR) ADC

Applications
Shunt-based polyphase energy meters
Solar inverters
Process monitoring
Smart power distribution units
Polyphase ac chargers
