ADS131M03IRUKR

Analog To Digital Converters (ADC) Overview

The ADS131M03IRUKR is a three-channel, synchronous sampling, 24-bit Sigma-Delta analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 3.6 V and features a serial peripheral interface (SPI). The device supports simultaneous sampling rates of 32 kSPS and 64 kSPS. It utilizes a WQFN-20 package for surface-mount installation. The component is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Provides three-channel simultaneous sampling capability for synchronized data acquisition across multiple inputs.
• Integrates a low-noise programmable gain amplifier (PGA) to amplify low-level signals directly at the input stage.
• Includes integrated channel-to-channel phase calibration registers to minimize signal chain errors.

Analog To Digital Converters (ADC) Applications

• Electricity metering systems requiring high-resolution voltage and current measurement
• Power monitoring applications utilizing direct connection to potential transformers or resistive dividers
• Circuit breaker control units needing precise energy calculation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUKR to confirm the WQFN-20 package variant and industrial temperature rating. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status through the official datasheet before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when three independent channels with synchronous sampling are required for power analysis. Compare against the ADS131M02 if only two channels are needed, or the ADS131M04 for four channels. Verify that the SPI interface compatibility matches the host microcontroller system constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS131M0x family of multi-channel ADCs designed specifically for energy metering. It shares architectural similarities with the ADS131M02 and ADS131M04, differing primarily in channel count. The series is optimized for applications demanding wide dynamic range and low power consumption in industrial environments.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS131M03IPWT serves as a pin-compatible alternative offering the same electrical performance in a TSSOP-20 package. Designers must verify footprint differences during PCB layout modifications when substituting between the WQFN and TSSOP packages.
