Overview
The REF2125IDBVR is a precision series voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 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 junction temperature range of -40°C to +125°C and is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive measurement circuits.
- Maintains stable output performance across wide industrial temperature variations through low drift characteristics.
- Utilizes a compact surface-mount footprint to facilitate space-constrained board layouts.
Applications
- Precision analog-to-digital converter (ADC) reference inputs
- Data acquisition systems requiring stable voltage baselines
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix IDBVR corresponds to the SOT-23-5 package and reel/cut-tape configuration. Confirm RoHS compliance status and humidity sensitivity level prior to assembly planning. Ensure input voltage limits are respected during system design validation.
Selection Notes
Select this component when a 2.5 V reference is required with 0.05% accuracy and 6 ppm/°C drift. Compare against the REF3425IDBVR if a six-pin SOT-23 package or shutdown functionality is preferred. Evaluate power consumption requirements against other family members for optimal efficiency.
Part Context
This part belongs to the REF21xx series of low-drift, low-power voltage references from Texas Instruments. It is designed for applications demanding high stability and small form factors. The series complements the broader REF3x and REF5x families offering various output voltages and pin configurations.
Replacement Considerations
The REF3425IDBVR offers similar electrical specifications but utilizes a SOT-23-6 package and includes a shutdown feature. Verify pinout compatibility and package dimensions before substituting.
