ADS131M04IPWT

Analog To Digital Converters (ADC) Overview

The ADS131M04IPWT is a four-channel, 24-bit sigma-delta analog-to-digital converter (ADC) from Texas Instruments. It features simultaneous sampling with a maximum data rate of 64 kSPS and an SPI interface. The device operates on dual power supplies ranging from 2.7 V to 3.6 V for both analog and digital domains. Key electrical specifications include a signal-to-noise ratio of 100 dB at 4 kSPS with unity gain, a total harmonic distortion of -100 dB, and a typical power consumption of 3.3 mW at 3 V. It utilizes a TSSOP-20 package and supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier with gains up to 128 for low-level signal amplification
• Built-in channel-to-channel phase calibration and offset/gain correction registers
• Optional cyclic redundancy check for data input, output, and register mapping integrity
• Internal low-drift voltage reference reducing printed circuit board area requirements

Analog To Digital Converters (ADC) Applications

• Commercial and residential energy meters
• Power distribution breakers
• Battery management systems
• Battery testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWT corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records for industrial-grade components intended for high-reliability applications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for multi-channel energy monitoring requiring high dynamic range and precise phase alignment. Compare against ADS131M02 or ADS131M03 if fewer channels are sufficient. Evaluate the integrated PGA and internal reference against external discrete solutions to determine overall system complexity and cost efficiency.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS131M series of specialized delta-sigma ADCs designed for metering applications. The IPWT suffix indicates surface-mount packaging in a TSSOP-20 footprint. It complements other variants like the ADS131M02 and ADS131M03 within the same family, offering distinct channel counts while maintaining consistent performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADS131M02 and ADS131M03, differing primarily in channel count. Verify functional equivalence regarding register maps and timing parameters before substitution.
