REF3225AIDBVTG4

Overview

The REF3225AIDBVTG4 is a series voltage reference integrated circuit manufactured by Texas Instruments, housed in an SOT-23-6 surface-mount package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 2.55V to 5.5V and draws a supply current of 135µA. It delivers a maximum output current of 10 mA and functions across a temperature range of -40°C to +125°C. Key noise specifications include 33µVp-p from 0.1Hz to 10Hz and 48µVrms from 10Hz to 10kHz.

Feature Summary

• Provides a stable fixed 2.5V reference output with high initial accuracy.
• Features low power consumption suitable for battery-operated applications.
• Delivers high drive capability with up to 10 mA output current.
• Ensures stability with low noise performance over wide bandwidths.

Applications

• Data acquisition systems requiring precise analog references
• Industrial process control instrumentation
• Portable measurement devices
• Medical equipment signal conditioning

Procurement Notes

Verify the complete part number including suffixes such as G4 to ensure compliance with specific packaging or environmental standards. Confirm that the component status aligns with design requirements, as this part may be marked as not recommended for new designs. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate precision and drive strength. Consider the SOT-23-6 package size constraints and the 135µA quiescent current against system power budgets. Evaluate the ±0.2% initial accuracy and 20ppm/°C temperature coefficient against application drift requirements compared to lower-drift alternatives like the REF34xx series.

Part Context

This component belongs to the REF32xx family of series voltage references from Texas Instruments. It shares common architectural features with other members like the REF3225AIDBVR, differing primarily in the reel packaging indicated by the 'VT' suffix. The family is designed for general-purpose precision applications where small footprint and low cost are prioritized alongside adequate performance.

Replacement Considerations

The REF3225AIDBVR is a direct functional substitute with identical electrical specifications but differs in tape-and-reel packaging configuration. Verify that the change in packaging format meets assembly line requirements without altering the circuit board layout or soldering profile.
