Description
General part information
ADS131M03 Series
The ADS131M03 is a three-channel, simultaneously-sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC) that offers wide dynamic range, low power, and energy-measurement-specific features, making the device an excellent fit for energy metering, power metrology, and circuit breaker applications. The ADC inputs can be directly interfaced to a resistor-divider network or a power transformer to measure voltage or to a current transformer, shunt, or a Rogowski coil to measure current.
The individual ADC channels can be independently configured depending on the sensor input. A low-noise, programmable gain amplifier (PGA) provides gains ranging from 1 to 128 to amplify low-level signals. Additionally, this device integrates channel-to-channel phase calibration and offset and gain calibration registers to help remove signal-chain errors.
A low-drift, 1.2-V reference is integrated into the device reducing printed circuit board (PCB) area. Optional cyclic redundancy checks (CRCs) on the data input, data output, and register map maintain communication integrity.
