REF2041QDDCRQ1

Overview

The REF2041QDDCRQ1 is a precision series voltage reference integrated circuit manufactured by Texas Instruments, designed for automotive applications. It operates within an input voltage range of 4.116 V to 5.5 V and delivers fixed output voltages of 2.048 V or 4.096 V with an initial accuracy of ±0.05%. The device features a low temperature coefficient of 8 ppm/°C and draws a supply current of 460 µA. It is housed in a SOT-23-THIN (TSOT-23-5) package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

Provides high-precision voltage referencing with ±0.05% initial accuracy
Features low temperature drift of 8 ppm/°C for stable performance
Designed for automotive environments with AEC-Q100 qualification

Applications

Automotive data acquisition systems
Precision analog-to-digital converter references
Medical instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix indicates the desired output voltage variant, as the base part number may correspond to multiple fixed voltage options. Confirm the TSOT-23-5 package marking matches the required revision. Ensure the component meets AEC-Q100 Grade 1 requirements for the intended automotive application environment.

Selection Notes

Select this component when a compact surface-mount solution is required for automotive circuits needing high stability. The low noise and tight tolerance make it suitable for sensitive measurement front-ends. Compare against shunt references if higher current capability is needed, noting this is a series type.

Part Context

This part belongs to the REF2041 family of dual-output, low-drift voltage references. It shares design characteristics with other members like the REF2025 and REF2033 but offers specific automotive-grade reliability. The QDDCRQ1 designation confirms its compliance with automotive quality standards and specific packaging configuration.
