Overview
The TL4051AIDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.225V to 10V using external resistors. The device features an initial accuracy of ±0.1% and a temperature coefficient of 50ppm/°C. It operates within a supply current range of 60µA (typical) to 12mA and maintains stability across all capacitive load conditions without requiring output capacitors. The component is housed in a compact SC-70-5 package and supports an industrial operating temperature range of -40°C to 85°C.
Feature Summary
- Adjustable output voltage configuration via external resistor divider
- High precision with ±0.1% initial accuracy and low temperature drift
- Micropower operation with minimal quiescent current consumption
- Intrinsic stability under all capacitive load conditions
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Process control instrumentation
- Precision audio applications
Procurement Notes
Verify the specific suffix 'IDCKR' against official Texas Instruments documentation to confirm the exact grade, package type, and tape-and-reel quantity. Ensure the procurement source provides valid traceability for the A-grade tolerance specification. Confirm that the component meets RoHS compliance standards required for the target assembly process.
Selection Notes
Select this component when high accuracy is required in space-constrained designs. The SC-70-5 package offers a small footprint suitable for portable devices. The adjustable output allows flexibility in setting reference voltages compared to fixed-output alternatives. Verify that the system's maximum cathode current does not exceed the 12mA limit during operation.
Part Context
This part belongs to the TL4051 family of precision micropower shunt voltage references. The family includes variants with different accuracies (A, B, C grades) and temperature ranges (I for industrial, Q for automotive/extended). The TL4051 series is designed to replace older Zener-based references, offering superior noise performance and lower temperature coefficients.
Replacement Considerations
Compatible substitutes include other TL4051 variants such as TL4051AQDCKR or LM4051AIM3X-ADJ/NOPB, provided pin compatibility and electrical specifications match the design requirements.
