Overview
The TL4050A25QDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 30 PPM/C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in a SC70-5 surface-mount package.
Feature Summary
- Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive measurement circuits.
- Designed for low-power applications through optimized micropower consumption characteristics.
- Ensures stable performance across wide industrial temperature ranges with low thermal drift.
Applications
- Portable battery-powered instrumentation requiring precise voltage references
- Data acquisition systems needing accurate analog-to-digital conversion references
- Medical devices demanding reliable signal conditioning components
Procurement Notes
Verify the specific suffix 'Q' indicates automotive qualification requirements if applicable to your design. Confirm the 'DCK' package code matches your PCB footprint constraints. Check for RoHS compliance status in the latest datasheet before finalizing procurement. Ensure the manufacturer source is authorized to guarantee component authenticity.
Selection Notes
Select this component when a 2.5 V reference with 0.1% accuracy is required in a compact SC70-5 package. Consider the 30 PPM/C temperature coefficient against your system's thermal stability needs. Evaluate the 15 mA maximum shunt current capability against your circuit's biasing requirements.
Part Context
This part belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades. The 'A' grade typically denotes tighter initial accuracy specifications compared to standard grades, while the 'Q' suffix often implies enhanced reliability or automotive qualification standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative shunt references based on pinout and electrical specifications.
