ADS1148QPWRQ1

Analog To Digital Converters (ADC) Overview

The ADS1148QPWRQ1 is an automotive-grade, low-power, high-precision analog-to-digital converter (ADC) from Texas Instruments. It features a sigma-delta architecture with 16-bit resolution and supports up to 2 kSPS data rates. The device integrates an 8-channel multiplexer, programmable gain amplifier (PGA), internal reference, and excitation current sources (iDACs). It operates on dual power supplies ranging from 2.7 V to 5.25 V for both analog and digital domains. The component is housed in a 28-pin TSSOP package and is qualified under AEC-Q100 standards for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated excitation current sources (iDACs) enable direct sensor excitation without external components.
• Built-in 50 Hz and 60 Hz rejection filters provide effective noise suppression for industrial applications.
• AEC-Q100 qualification ensures reliability and compliance with automotive industry requirements.

Analog To Digital Converters (ADC) Applications

• Automotive sensor signal conditioning
• Industrial process control systems
• Precision measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status and confirm the 'PWR' designation corresponds to the TSSOP-28 package variant. Ensure compatibility with system voltage levels and interface protocols before integration. Cross-reference official datasheets for pinout configurations and thermal specifications to validate design suitability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when automotive certification is mandatory and high channel count is required. Compare power consumption metrics against non-automotive alternatives if weight or thermal constraints are critical. Verify that the integrated PGA and iDAC capabilities meet the specific sensor interface requirements without needing additional support circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS114x family of precision ADCs designed for demanding measurement applications. It shares architectural similarities with commercial variants but includes enhanced durability and qualification testing for automotive environments. The QPWRQ1 suffix specifically denotes the automotive grade and surface-mount packaging configuration.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1148IPWR serves as the commercial equivalent with similar electrical characteristics but lacks automotive qualification. ADS1148QPWRQ1 is the direct automotive counterpart. Verify package compatibility and software register settings when migrating between commercial and automotive grades.
