Overview
The REF3320AIDBZTG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.048 V with an initial accuracy of 0.15%. It features a low temperature coefficient of 30 ppm/°C and operates on a supply voltage up to 5.5 V. The device draws a typical quiescent current of 3.9 μA, making it suitable for battery-powered applications. It supports a maximum shunt current of 5 mA and functions reliably within an extended temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 footprint, it ensures stable performance in space-constrained designs.
Feature Summary
- Provides a fixed 2.048 V output with high initial accuracy
- Low power consumption optimized for portable devices
- Stable performance across wide industrial temperature ranges
Applications
- Portable instrumentation requiring precise voltage references
- Battery-operated measurement systems
- Data acquisition systems needing stable analog references
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm package type matches SOT-23-3 requirements. Check for end-of-life notices or obsolescence warnings associated with this specific revision. Ensure humidity sensitivity class aligns with storage and reflow soldering constraints defined in the datasheet.
Selection Notes
Select this component when a fixed 2.048 V reference is required with minimal temperature drift. Compare against other REF33xx variants if different output voltages are needed. Consider the SOT-23-3 package size for board space limitations. Verify input voltage does not exceed the 5.5 V maximum rating during operation.
Part Context
This part belongs to the REF33xx family of low-power, precision voltage references from Texas Instruments. These devices are designed for applications requiring high stability and low noise. The REF3320 variant specifically provides a 2.048 V output, distinguishing it from other members of the series that offer different fixed voltages.
Replacement Considerations
Check for direct pin-compatible substitutes within the REF33xx family offering similar voltage and accuracy. Verify thermal and electrical specifications match before substituting.
