Overview
The REF3112AIDBZR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.25 V with an initial accuracy of 0.2%. It features a low temperature coefficient of 20 ppm/°C and operates within an input voltage range of 1.8 V to 5.5 V. The device draws a typical supply current of 100 µA and supports a maximum shunt current of 10 mA. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Provides stable 1.25 V output with high initial accuracy
- Features low temperature drift for thermal stability
- Operates efficiently with minimal quiescent current consumption
Applications
- Portable instrumentation circuits
- Battery-powered measurement systems
- Data acquisition signal conditioning
Procurement Notes
Verify the suffix 'DBZR' confirms the reel packaging format distinct from the tape-and-reel variant. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the specific temperature grade and accuracy bin required for your design specifications.
Selection Notes
Select this component when a balance of moderate power consumption and high precision is required. It offers superior temperature stability compared to lower-cost alternatives while maintaining a small footprint suitable for space-constrained designs. Consider the 10 mA load capability for driving downstream circuitry without external buffering.
Part Context
This part belongs to the REF31xx family of micropower voltage references designed for general-purpose applications. It shares the same pinout and form factor as other members like the REF3112AIDBZT but differs in packaging configuration. The series is optimized for applications requiring long-term stability and low noise in portable electronic devices.
Replacement Considerations
The REF3112AIDBZT serves as a direct functional substitute with identical electrical characteristics, differing primarily in shipping packaging format.
