Overview
The REF3020AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.048 V. It features an initial accuracy of 0.2% and a temperature coefficient of 50 ppm/°C. The device operates with a maximum supply current of 50 µA and supports input voltages up to 5.5 V. It is housed in a SOT-23-3 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Provides stable 2.048 V reference output with low temperature drift
- Operates with minimal quiescent current for power efficiency
- Designed for high initial accuracy in compact surface-mount packaging
Applications
- Precision analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) voltage sources
- Portable instrumentation requiring low power consumption
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'A' grade designation matches required accuracy specifications. Ensure compatibility with SOT-23-3 footprints during PCB layout. Check manufacturer documentation for latest revision status before finalizing procurement.
Selection Notes
Select this component when a 2.048 V output is required with tight tolerance and low power constraints. Compare against other REF30xx variants if different voltage levels or noise performance are needed. Verify that the 50 ppm/°C drift meets system thermal stability requirements across the operating temperature range.
Part Context
This part belongs to the REF30 series of micropower voltage references. It shares the same core architecture as the REF3020AIDBZR but differs in packaging format. The series is designed for battery-powered applications where low current draw and long-term stability are critical.
Replacement Considerations
The REF3020AIDBZR is a compatible alternative with identical electrical characteristics, differing only in reel versus cut-tape packaging. Other REF3020 variants may offer different grades or packages but must be verified for pinout and parameter equivalence.
