Overview
The REF1930AIDDCT is a dual-output series voltage reference manufactured by Texas Instruments, housed in a SOT-23-Thin-5 package. It provides fixed outputs of 3V and Vref/2 (1.5V). Key electrical parameters include an initial accuracy of 0.1%, a temperature coefficient of 25 ppm/C, and a maximum input voltage of 5.5V. The device operates with a quiescent current of 360 uA and supports a maximum shunt current of 20 mA. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Dual-output architecture providing both full reference voltage and half-reference voltage simultaneously.
- High precision performance with tight initial accuracy tolerance for sensitive analog circuits.
- Low power consumption design suitable for battery-operated or space-constrained applications.
Applications
- Data acquisition systems requiring stable dual-rail references.
- Industrial process control instrumentation.
- Medical equipment signal conditioning.
Procurement Notes
Verify the specific suffix 'DDC' indicates the tape-and-reel packaging format compatible with automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the required output voltage configuration and package type exactly to avoid functional mismatches in production.
Selection Notes
Select this component when dual independent voltage rails are needed from a single reference source without external resistor dividers. Compare against single-output alternatives if only one rail is required to optimize board space. Consider the 25 ppm/C drift specification against application thermal stability requirements. Verify that the 360 uA supply current fits within the system's total power budget constraints.
Part Context
This device belongs to the REF19x family of low-drift, low-power voltage references from Texas Instruments. It shares the SOT-23-Thin-5 form factor with other members like the REF1925 and REF1941, offering pin-compatible options for different voltage outputs while maintaining similar performance characteristics and package dimensions for flexible design implementation.
Replacement Considerations
The REF1930AIDDT serves as a cut-tape alternative to the reel-packaged REF1930AIDDCT. Other family members such as the REF1925AIDDCT and REF1941AIDDCT offer different voltage outputs but share the same package and general interface specifications.
