ADS131M08/ADS131M08-Q1 8-Channel Delta-Sigma ADC Texas Instruments ADS131M08/ADS131M08-Q1 8-Channel Delta-Sigma Analog-to-Digital Converter (ADC) is an eight-channel, simultaneously-sampling, 24-bit, delta-sigma (ΔΣ) ADC. This ADC offers a wide dynamic range, low-power, and energy-measurement-specific features. These features make the device an excellent fit for energy metering, power metrology, and circuit breaker applications. The ADC inputs can be directly interfaced with a resistor-divider network or a power transformer to measure voltage or to a current transformer, 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. This device integrates channel-to-channel phase calibration and offset and gain calibration registers to help remove signal-chain errors. A low-drift, 1.2V reference is integrated into the ADS131M08/ADS131M08-Q1, reducing the printed circuit board (PCB) area. Cyclic redundancy check (CRC) options can be individually enabled on the data input, data output, and register map to ensure communication integrity. The Texas Instruments ADS131M08-Q1 devices are AEC-Q100 qualified for automotive applications.
