REF3425TIDBVR

Overview

The REF3425TIDBVR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of 0.05%. It operates within an input voltage range of 2.55 V to 12 V and draws a typical supply current of 72 uA. The device features a low temperature coefficient of 2.5 PPM/C and functions reliably across an extended industrial temperature range from -40 C to +125 C. Packaged in a compact SOT-23-6 surface-mount format, it includes a shutdown capability for power management.

Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 2.5 V reference with high accuracy is required in a small footprint. Consider the 72 uA quiescent current for power-sensitive designs. Ensure the input voltage remains within the specified 2.55 V to 12 V range. Verify thermal management needs for operation near the upper temperature limit of 125 C.

Part Context

This device belongs to the REF34xx family of low-drift voltage references from Texas Instruments. It shares architectural similarities with other members like the REF3430 and REF3433, differing primarily in output voltage and specific drift characteristics. The TIDBVR suffix indicates a tape-and-reel packaging configuration in an SOT-23-6 package optimized for automated surface-mount assembly.

FAQ
