Overview
The TL431TDA2 is a precision programmable shunt voltage reference die manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 2.495 V to 36 V with high accuracy. The device features low output noise and a typical output impedance, ensuring stable regulation in sensitive circuits. Designed for power and space-constrained applications, it operates with a low quiescent current of 1 μA. The component is supplied as a bare die, requiring integration into custom substrates or packages.
Feature Summary
- Provides precise programmable reference voltage functionality
- Features ultra-low operating current for energy efficiency
- Delivers low output noise characteristics for signal integrity
Applications
- Power supply feedback loops
- Battery-operated equipment
- Space-sensitive electronic designs
Procurement Notes
Verify the specific revision level and lot traceability when sourcing this die component. Confirm that the supplier provides documentation regarding the commercial production baseline processing standards. Ensure compatibility with your intended substrate or packaging solution prior to procurement.
Selection Notes
Select this component when minimizing board space and power consumption are critical design constraints. The bare die format requires careful consideration of thermal management and mechanical mounting strategies within the final assembly process compared to packaged alternatives.
Part Context
This part belongs to the TL431 family of precision programmable references. Unlike standard packaged versions, the TDA2 suffix indicates a die configuration intended for direct integration into specialized modules or hybrid circuits, offering flexibility in form factor optimization.
Replacement Considerations
Direct functional equivalents include other TL431 series variants such as TL431ACD or LM431AIZ/NOPB, though these are packaged components rather than bare dies. Substitution requires adapting the mechanical interface and thermal dissipation methods.
