Overview
The REF35250QDBVR is a high-precision series voltage reference from the Texas Instruments REF35 family, housed in a 6-pin SOT-23 package. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.05%. The device features ultra-low quiescent current consumption of 650nA and a maximum temperature coefficient of 12ppm/°C across the -40°C to +105°C range. It supports input voltages up to 6V and offers long-term stability of 40ppm at 1k hours.
Feature Summary
- Ultra-low power consumption with typical quiescent current of 650nA
- High precision with ±0.05% initial accuracy and low drift
- Integrated enable pin for shutdown mode operation
- Noise reduction pin available for low-noise applications
Applications
- Flow transmitters
- Blood glucose monitors
- Servo drive control modules
- Power quality analyzers
- Process analytics systems
Procurement Notes
Verify the specific suffix 'QDBVR' corresponds to the standard commercial grade SOT-23-6 package variant. Confirm that the required operating temperature range aligns with the specified -40°C to +105°C performance limits. Ensure input voltage requirements do not exceed the absolute maximum rating of 6V. Check for moisture sensitivity handling requirements during assembly.
Selection Notes
Select this component when a fixed 2.5V reference is required with minimal power draw. The SOT-23-6 package suits space-constrained designs. Consider the noise reduction pin if lower low-frequency noise is needed compared to standard operation. Verify load regulation requirements against the sourcing and sinking current capabilities.
Part Context
This part belongs to the REF35 family of nanopower, low-drift, high-precision series references. The family includes various output voltage options ranging from 1.024V to 5.0V. Other packages include WCSP, while other variants like REF35250QDBVRQ1 offer automotive qualification.
Replacement Considerations
