Dual-Channel 24-Bit Delta-Sigma ADC for Energy Metering, Power Monitoring, and Precision Signal Measurement
The ADS131M02IRUKR is a high-precision 24-bit delta-sigma Analog to Digital Converter designed for accurate measurement of voltage and current in energy monitoring and industrial sensing applications. With two simultaneously sampling channels, this ADC enables precise time-aligned measurements, which is essential for power metrology, smart energy meters, and power quality monitoring systems.
This device integrates a low-noise programmable gain amplifier, calibration registers, and advanced signal-processing features that simplify high-accuracy measurement system design. Its wide dynamic range and low power consumption make it suitable for applications such as circuit breakers, energy meters, industrial monitoring equipment, and precision instrumentation. The compact WQFN-20 package also allows designers to build high-performance measurement systems in space-constrained designs.
