ADS131M06IRSNT

Analog To Digital Converters (ADC) Overview

The ADS131M06IRSNT is an eight-channel, simultaneous-sampling, 24-bit Sigma-Delta analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a WQFN-32 package and operates on dual power supplies ranging from 2.7 V to 3.6 V for both analog and digital domains. The device supports data rates up to 32 kSPS with differential inputs. Key electrical specifications include a signal-to-noise ratio of 80 dB or 101 dB depending on the gain setting, a gain error of 0.3%, and a typical power consumption of 6 mW. It integrates an internal 1.25 V reference and functions within an industrial temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel simultaneous sampling architecture ensures precise phase alignment across all inputs.
• Integrated low-drift internal voltage reference reduces external component count and PCB area.
• Built-in channel-to-channel phase calibration and offset/gain correction registers minimize signal chain errors.
• Optional cyclic redundancy check (CRC) in data output and register maps guarantees communication integrity.

Analog To Digital Converters (ADC) Applications

• Electricity metering systems requiring high-precision multi-phase measurements
• Power monitoring applications involving voltage and current sensing via transformers
• Breaker control units utilizing Rogowski coils or current transformers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSNT' corresponds to the WQFN-32 package and tape-and-reel shipping configuration. Confirm that the internal reference voltage is set to 1.25 V as specified in the datasheet. Ensure compatibility with SPI interface requirements before integration into the host system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight synchronized channels are required for high-resolution energy measurement. Compare against the ADS131M08 if additional channels are needed, or the ADS131M04 for reduced pin counts. Verify that the 32 kSPS maximum data rate meets the application's bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS131M0x family of high-performance, multi-channel ADCs designed specifically for utility metering. It shares architectural similarities with the ADS131M08 but provides six active channels instead of eight. The device complements Texas Instruments' portfolio of analog front-end solutions for smart grid infrastructure.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS131M08IRSNR serves as a functional substitute offering eight channels instead of six. The ADS131M04 series provides four channels with similar performance characteristics. Verify pinout compatibility and software register mapping differences when migrating between these variants.
