REF3425IDBVR

Overview

The REF3425IDBVR is a precision series voltage reference from Texas Instruments, delivering a fixed 2.5 V output with an initial accuracy of ±0.05%. It features a low temperature coefficient of 6 ppm/°C and operates within an input voltage range of 3 V to 12 V. The device draws a typical supply current of 95 µA and supports a maximum load current of 10 mA. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision voltage regulation with tight initial accuracy tolerance for sensitive analog circuits.
• Features low power consumption suitable for battery-operated and portable applications.
• Includes a shutdown capability to minimize energy usage during inactive periods.

Applications

• Data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Automotive sensor signal conditioning

Procurement Notes

Verify the specific suffix IDBVR confirms the industrial temperature grade and SOT-23-6 packaging configuration. Ensure compatibility with moisture sensitivity level requirements for your assembly process. Confirm that the 10 mA output current meets your load demands. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when precise voltage stability is critical under varying thermal conditions. The 6 ppm/°C drift rate offers superior performance compared to standard references. Consider the SOT-23-6 footprint for space-constrained PCB layouts. Evaluate the 95 µA quiescent current against system power budgets.
