ADS131M04IRUKR

Analog To Digital Converters (ADC) Overview

The ADS131M04IRUKR is a four-channel, 24-bit analog-to-digital converter (ADC) utilizing sigma-delta architecture. It supports simultaneous sampling with a maximum data rate of 64 kSPS per channel and features an SPI digital interface. The device operates on dual power supplies: analog AVDD and digital DVDD, both ranging from 2.7 V to 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 100 dB, a gain error of 0.1% FSR, and integral nonlinearity (INL) of 6 ppm. It functions within a temperature range of -40°C to +125°C and is housed in a 20-pin WQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel simultaneous sampling capability for synchronized multi-phase measurements
• High-resolution 24-bit sigma-delta conversion architecture
• Integrated programmable gain amplifier (PGA) for flexible input scaling
• Low power consumption design suitable for battery-operated systems

Analog To Digital Converters (ADC) Applications

• Two-phase Rogowski coil based electricity metering
• Industrial process control data acquisition
• Medical instrumentation requiring high precision
• Vibration monitoring and structural health assessment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUKR corresponds to the 20-WQFN (3x3) package variant when sourcing. Confirm RoHS compliance status through official Texas Instruments documentation prior to integration. Ensure supply chain partners provide valid traceability records. Validate that the component meets the required operating temperature range for the target environment. Cross-reference datasheet revisions to ensure feature consistency.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring four independent channels with simultaneous sampling accuracy. Compare against the ADS131M02 if only two channels are necessary to optimize cost. Consider the IPWR TSSOP-20 package if board space constraints differ from the WQFN footprint. Verify that the 100 dB SNR meets system noise floor requirements at the desired output data rate.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS131Mxx family of low-power, 24-bit ADCs designed for metrology and industrial applications. It shares architectural similarities with the ADS131M02 but provides additional channel capacity. The device complements Texas Instruments' portfolio of precision data converters, offering integrated signal conditioning and digital filtering capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS131M04IPWR serves as a pin-compatible alternative featuring a TSSOP-20 package instead of the WQFN form factor. Both devices share identical electrical specifications and functionality. Verify mechanical fitment and thermal dissipation characteristics when substituting between package types.
