Overview
The TL4050A25IDBZTG4 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 50 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 SOT-23-3 package.
Feature Summary
- Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive measurement applications.
- Designed for low-power consumption, utilizing micropower architecture suitable for battery-operated systems.
- Ensures stable performance across wide industrial temperature ranges with controlled thermal drift characteristics.
Applications
- Portable instrumentation requiring precise analog-to-digital converter references
- Battery-powered data acquisition systems
- Industrial process control loops
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the environmental constraints of the final assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a 2.5 V reference with ±0.1% accuracy is required in a compact SOT-23-3 package. Consider the 50 PPM/°C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum shunt current against the circuit load requirements. Compare against other TL4050 variants if different accuracy grades or output voltages are needed.
Part Context
This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades (A, B, C) packaged in small form factors like SC-70 and SOT-23. The TL4050 series is designed to replace larger, higher-power references in space-constrained designs while maintaining high precision.
