REF35102QDBVR

Overview

The REF35102QDBVR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.024 V with an initial accuracy of 0.05%. It features a low quiescent current of 650 nA and a temperature coefficient of 12 ppm/°C. The device operates within a supply voltage range up to 6 V and supports a shutdown function. It is housed in a SOT-23-6 package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides high-precision voltage regulation with 0.05% initial accuracy
• Optimized for low-power applications via 650 nA quiescent current consumption
• Ensures stable performance over wide thermal variations with 12 ppm/°C drift
• Integrates a shutdown mode to minimize power usage during inactive periods

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter (ADC) references
• Industrial process control instrumentation
• Medical diagnostic equipment requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status per official datasheets. Confirm the SOT-23-6 package dimensions match PCB footprint requirements. Ensure input voltage does not exceed maximum ratings. Check humidity sensitivity handling instructions for storage and reflow processes. Validate that the 12 ppm/C drift specification meets system thermal stability needs.

Selection Notes

Choose this component when a fixed 1.024 V reference is required with tight initial tolerance. Select for designs prioritizing ultra-low standby current due to the 650 nA quiescent draw. Consider the SOT-23-6 form factor for space-constrained surface-mount layouts. Verify compatibility with ADC input ranges and ensure the 12 ppm/C drift aligns with long-term calibration requirements.

Part Context

This part belongs to the REF35 family of precision voltage references designed for demanding industrial and automotive environments. It complements other REF35 variants offering different output voltages while maintaining consistent low-power characteristics. The series is engineered to provide reliable performance in applications where voltage stability and minimal power consumption are critical design constraints.

Replacement Considerations

Consult official substitution guides for compatible REF35 series alternatives. Verify pinout compatibility before replacing with similar packages. Ensure electrical parameters such as drift and accuracy meet or exceed original specifications.
