ADS131M06IRSNR

Analog To Digital Converters (ADC) Overview

The ADS131M06IRSNR is a six-channel, simultaneously-sampling, 24-bit delta-sigma analog-to-digital converter manufactured by Texas Instruments. It operates with analog and digital supply voltages ranging from 2.7 V to 3.6 V. The device supports programmable data rates up to 32 kSPS and offers programmable gain settings from 1 to 128. Key electrical specifications include a signal-to-noise ratio of 101 dB at gain 1, a dynamic range of 102 dB, and total harmonic distortion of -100 dB. It features an integrated low-drift 1.2-V internal voltage reference and optional cyclic redundancy checks for communication integrity. The component is housed in a 32-pin WQFN package and functions within an industrial temperature range of –40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and availability. Ensure the procurement documentation matches the exact part number ADS131M06IRSNR to avoid discrepancies in pin configuration or thermal characteristics. Cross-reference the datasheet revision history for any updates to electrical parameters or recommended operating conditions prior to finalizing purchase orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-precision energy metrology requires simultaneous multi-channel sampling. The integrated PGA eliminates external amplifiers for low-level signals, while the internal reference reduces PCB area. Consider the WQFN package for compact designs requiring efficient thermal dissipation. Verify that the system clock frequency aligns with the desired data rate and power mode requirements specified in the electrical characteristics table.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS131M0x family of delta-sigma ADCs designed for energy measurement applications. It shares functional similarities with the ADS131M08 but provides six channels instead of eight. The RSNR suffix indicates the 32-pin leadless WQFN package variant. It serves as a direct replacement for previous generation components in metering designs requiring high resolution and low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS131M06PBS is the TQFP package equivalent. No other direct substitutes are confirmed in public documentation.
