Overview
The TL4051BIDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225 V with an initial accuracy of 0.2%. The device features a temperature coefficient of 50 ppm/°C and operates within an extended industrial temperature range from -40°C to +125°C. It is housed in a compact SC-70-5 surface-mount package. The maximum shunt current is rated at 12 mA, ensuring stable performance across various load conditions without requiring external output capacitors.
Feature Summary
- Provides a fixed 1.225 V output with 0.2% initial accuracy
- Operates stably under all capacitive load conditions without external compensation
- Delivers low noise and low dynamic impedance for high-precision applications
Applications
- Data acquisition systems
- Portable instrumentation
- Battery-powered equipment
Procurement Notes
Verify the specific grade suffix 'B' corresponds to the required 0.2% tolerance during procurement. Confirm the 'IDCKR' suffix indicates the SC-70-5 package and reel packaging format. Ensure the component meets RoHS compliance standards for your manufacturing process. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your design requirements.
Selection Notes
Select this component when a fixed 1.225 V reference is needed with tighter accuracy than the C-grade variant but lower cost than the A-grade. The SC-70-5 package offers space savings compared to larger packages. The extended temperature range supports operation in harsh environments where standard industrial ranges are insufficient.
Part Context
This part belongs to the TL4051 family of micropower shunt voltage references. It shares architectural similarities with the TL4050 series but offers different output options and package configurations. The TL4051 series is designed for applications requiring low power consumption and high stability in compact form factors.
Replacement Considerations
TL4051AIDCKR offers higher accuracy (0.1%). TL4051CIDCKR provides lower accuracy (0.5%) at potentially lower cost. Verify thermal and electrical compatibility before substitution.
