ADS131M08IPBSR

Analog To Digital Converters (ADC) Overview

The ADS131M08IPBSR is an eight-channel, simultaneous-sampling, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a maximum sampling rate of 32 kSPS and features differential inputs. The device utilizes SPI for digital communication and includes an internal 1.2 V reference. It supports analog and digital supply voltages ranging from 2.7 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of up to 101 dB and a spurious-free dynamic range of 103 dB. The component is housed in a 32-pin WQFN package and is rated for industrial operating temperatures between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated low-drift 1.2 V internal voltage reference reduces printed circuit board area requirements.
• Programmable gain amplifier provides selectable gain factors from 1 to 128 to amplify low-level sensor signals.
• Built-in channel inter-phase calibration, offset, and gain calibration registers help eliminate signal chain errors.
• Optional cyclic redundancy check in data input, output, and register maps ensures communication integrity.

Analog To Digital Converters (ADC) Applications

• Electricity metering systems
• Power metering applications
• Circuit breaker implementations

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPBSR indicates the reel packaging variant distinct from the tray-packaged IPBS version. Confirm that the ordering part number matches the required tape-and-reel quantity specifications for automated assembly lines. Ensure compatibility with the target PCB footprint for the 32-pin WQFN package before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous multi-channel acquisition is required for high-precision energy monitoring. The integrated PGA and calibration features simplify designs involving current transformers or Rogowski coils. Verify that the 32 kSPS sampling limit meets the bandwidth requirements of the specific power quality analysis application.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS131M08 family of precision ADCs. It shares core architectural similarities with the ADS131M08 and ADS131M08IPBS but differs in packaging configuration. The IPBSR designation specifically denotes the wafer-scale packaged variant supplied in reels, distinguishing it from the TQFP tray options within the same product series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS131M08IPBS serves as a direct functional equivalent differing only in tray packaging rather than electrical characteristics.
