ADS1261BQWRHMRQ1

Overview

The ADS1261BQWRHMRQ1 is an automotive-grade, 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features a multiplexer, programmable gain amplifier (PGA), and internal reference. The device supports up to 10 differential or 20 single-ended input channels with a maximum sampling rate of 40 kSPS. It operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply range of 2.7 V to 5.25 V. The component is housed in a 32-pin VQFN package and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

Integrated excitation current sources (iDACs) for direct sensor driving
Built-in temperature sensor and GPIO capabilities
Hardware-configurable 50/60 Hz line frequency rejection
Sigma-delta architecture with integrated PGA and multiplexer

Applications

Automotive weigh scale systems
Industrial process control monitoring
Precision bridge measurement applications

Procurement Notes

Verify the specific suffix QWRHMRQ1 against official Texas Instruments documentation to confirm automotive qualification and package type. Ensure compatibility with system power supplies and SPI interface requirements before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.

Selection Notes

Select this component when high-resolution data acquisition is required in automotive environments. The 24-bit resolution and low noise performance suit precision sensing tasks. Consider the 10-channel multiplexing capability if multiple sensors need sequential monitoring within a single microcontroller interface.

Part Context

This part belongs to the ADS1261 family of precision ADCs designed for demanding measurement applications. The 'Q1' suffix indicates AEC-Q100 automotive qualification, while 'B' typically denotes a specific bin or revision within the series. It serves as a robust solution for replacing older discrete ADC solutions in vehicle instrumentation.
