Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BQDGSRQ1 against the official Texas Instruments datasheet to confirm package type, temperature range, and automotive qualification status. Ensure compatibility with existing I2C bus configurations and voltage levels. Check for recent lifecycle notices or obsolescence warnings before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and automotive reliability are required in a minimal footprint. Compare against the standard ADS1113 if automotive qualification is not necessary. Consider the I2C interface constraints and address configuration needs. Evaluate power budget requirements against the specified operating current at the desired data rate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of precision ADCs from Texas Instruments. It shares architectural similarities with the ADS1013 and ADS1115 but offers higher resolution. The Q1 suffix indicates automotive grade, while the BQDGSR variant specifies the VSSOP-10 package and reel packaging. It serves as a direct upgrade path for legacy 12-bit solutions requiring improved accuracy.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1113IDGSRQ1 is a verified alternative within the same family, differing primarily in commercial versus automotive grading. The ADS1115BQDGSRQ1 offers additional channels but maintains similar performance characteristics. Verify pinout compatibility and software register settings when substituting.
