Overview
The TL4051AQDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It features an adjustable output voltage range from 1.225V to 10V, set via external resistors. The device offers high accuracy with an initial tolerance of ±0.1% and a low temperature coefficient of 50ppm/°C. It operates within an extended industrial temperature range of -40°C to 125°C and requires a minimum cathode current of 65µA. The component is housed in a compact SC-70-5 surface-mount package.
Feature Summary
- Provides stable reference voltage without requiring external output capacitors across all capacitive load conditions
- Delivers high precision with ±0.1% initial tolerance and low temperature drift characteristics
- Supports flexible voltage setting through external resistor dividers within the specified range
Applications
- Data acquisition systems
- Battery-powered equipment
- Precision audio applications
- Process control instrumentation
Procurement Notes
Verify the specific suffix 'Q' indicates automotive qualification and 'K' denotes the SC-70-5 package configuration. Confirm the 'T' suffix corresponds to tape-and-reel packaging for automated assembly. Ensure the part number matches the required ±0.1% accuracy grade and extended temperature rating before procurement.
Selection Notes
Select this component when high accuracy and stability are required in space-constrained designs. The SC-70-5 package offers a smaller footprint compared to SOT-23 alternatives. Choose this model over fixed-voltage references when system design necessitates a specific reference level between 1.225V and 10V.
Part Context
This device belongs to the TL4051 family of micropower shunt voltage references. It shares core architectural similarities with other variants like the TL4051C series but distinguishes itself through tighter initial tolerance specifications and extended temperature operation capabilities suitable for demanding environments.
Replacement Considerations
Direct substitutes include TL4051AQDCKR (cut tape version) or TL4051AQDCKRG4 (lead-free variant). For pin-compatible alternatives with different tolerances, consider TL4051BQDCKT or TL4051CQDCKT.
