REF3430IDBVR

Overview

The REF3430IDBVR is a precision series voltage reference manufactured by Texas Instruments, housed in a compact SOT-23-6 surface-mount package. It delivers a fixed output voltage of 3 V with an initial accuracy of 0.05%. The device features a low temperature coefficient of 6 PPM/°C and supports a maximum input voltage of 12 V. It operates within a wide industrial temperature range from -40°C to +125°C and includes a shutdown function for power management.

Feature Summary

Provides stable 3 V reference output with high initial accuracy
Features low drift characteristics suitable for precision applications
Includes integrated shutdown capability for power optimization

Applications

Data acquisition systems requiring precise voltage references
Industrial process control instrumentation
Medical equipment signal conditioning circuits
Battery-powered measurement devices

Procurement Notes

Verify the specific suffix IDBVR corresponds to the SOT-23-6 package and commercial grade specifications. Confirm RoHS compliance status through official documentation before integration. Ensure supply chain sources provide genuine Texas Instruments components to maintain performance reliability and avoid counterfeit risks in critical designs.

Selection Notes

Select this component when a fixed 3 V output is required with tight initial accuracy and moderate temperature stability. The SOT-23-6 package offers space efficiency for portable designs. Consider the REF3430TIDBVR variant if lower temperature coefficients are necessary for extended operating ranges or higher precision requirements.

Part Context

This part belongs to the REF3430 family of precision voltage references designed for general-purpose analog signal processing. It serves as a stable reference source for ADCs and DACs in mixed-signal systems. The device integrates bandgap reference technology to ensure consistent performance across varying load conditions and environmental temperatures.
