Overview
The LM4040A50IDBZR is a precision micropower shunt voltage reference from Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 100ppm/°C. The device operates within a cathode current range of 45μA to 15mA and functions over an ambient temperature range of –40°C to 85°C. It is housed in a space-saving SOT-23-3 package.
Feature Summary
- Offers tight output tolerances and low temperature coefficients for high precision applications
- Operates stably with all capacitive loads without requiring external output capacitors
- Features low dynamic impedance and low noise characteristics
Applications
- Data-Acquisition Systems
- Energy Infrastructure
- Analog Input Module
- Field Transmitters
- Precision Audio
Procurement Notes
Verify the specific suffix 'DBZR' corresponds to the SOT-23-3 surface-mount package and reel packaging configuration. Confirm that the 'A' grade designation matches the required 0.1% initial accuracy and 100ppm/°C temperature coefficient specifications for your design. Ensure the industrial temperature range (-40°C to 85°C) meets your environmental requirements.
Selection Notes
Select this component when a fixed 5V reference with high precision (±0.1%) is required in a compact footprint. It is suitable for portable applications due to its micropower consumption, starting at a typical minimum cathode current of 45μA. Consider the extended temperature range variants if operation beyond 85°C is necessary.
Part Context
This part belongs to the LM4040 series of shunt voltage references, which are designed as versatile, easy-to-use references. The series utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to achieve various tolerance grades. The LM4040A50IDBZR specifically represents the A-grade version with 5V output in the SOT-23-3 package.
