REF3425MDBVTEP

Overview

The REF3425MDBVTEP is a low-drift, low-power series voltage reference IC manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.05% and a temperature coefficient of 2.5 ppm/°C. The device operates within an input voltage range of 2.55 V to 12 V and draws a typical supply current of 95 µA. It supports a maximum load current of 10 mA and functions reliably across an extended temperature range from -55°C to +125°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Delivers high precision with ±0.05% initial accuracy and low drift characteristics for stable reference performance.
• Features ultra-low power consumption with a supply current of 95 µA, suitable for battery-operated applications.
• Designed for small-footprint integration using the compact SOT-23-6 surface-mount package.

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'DBVTEP' to confirm the SOT-23-6 package and tape-and-reel quantity. Ensure compatibility with your PCB footprint design. Check moisture sensitivity levels if storage conditions exceed specified limits. Confirm that the operating temperature range meets your environmental requirements. Validate input voltage constraints against your power supply rails.

Selection Notes

Select this component when low power consumption and high precision are critical. The 2.5 V output suits ADC/DAC interfaces requiring mid-rail references. Consider the SOT-23-6 package for space-constrained designs. Evaluate the 10 mA load capability against system current demands. Compare temperature coefficients if extreme stability over wide thermal ranges is required.

Part Context

This part belongs to the REF34xx family of low-drift voltage references from Texas Instruments. It shares architectural similarities with other members like the REF3425TIDBVR but differs in packaging and reel configuration. The family targets applications needing stable references without the complexity of adjustable regulators. It complements higher-performance series like the REF50xx which offer lower noise at higher power costs.

Replacement Considerations

The REF3425TIDBVR is a functional substitute offering identical electrical specifications. Verify package compatibility as both use SOT-23-6. Ensure reel quantities match assembly line requirements. No pinout changes are expected between these variants within the same series.
