Overview
The TL4050B10IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.2%. The device operates within a temperature range of -40°C to 85°C and features a temperature coefficient of 50ppm/°C. Electrical specifications include a maximum cathode current of 103 µA, a noise level of 150µVrms in the 10Hz to 10kHz bandwidth, and a maximum output current capability of 15 mA. It is housed in a compact SC-70-5 surface-mount package.
Feature Summary
- Delivers high-precision voltage regulation with ±0.2% initial accuracy for stable reference applications.
- Designed for low-power consumption with a micropower quiescent current profile suitable for battery-operated systems.
- Maintains stability across industrial temperature ranges with a low temperature coefficient of 50ppm/°C.
Applications
- Portable instrumentation requiring precise analog references
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance and REACH status prior to integration. Check for specific ordering suffixes that may indicate packaging variations. Ensure the SC-70-5 footprint matches the design layout. Validate datasheet revisions against the production batch date.
Selection Notes
Select this component when a 10V fixed reference is required in space-constrained designs. The SC-70-5 package offers a small form factor compared to larger alternatives. Consider the 103 µA cathode current for power budget calculations. Evaluate the 150µVrms noise specification against system sensitivity requirements. Compare thermal performance within the -40°C to 85°C operating range.
Part Context
This part belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family includes various output voltages and accuracy grades. The 'B' designation typically indicates the ±0.2% accuracy grade. The 'DCKR' suffix denotes the SC-70-5 package and tape-and-reel shipping configuration. This series is designed for general-purpose precision applications.
Replacement Considerations
Direct substitutes include other TL4050 variants with different voltage outputs or accuracy grades, provided the pinout remains compatible. Verify electrical parameters such as noise and temperature coefficient match application needs before substitution.
