Overview
The LM336BMX-2.5 is a precision shunt voltage reference diode manufactured by Texas Instruments, operating at a nominal output of 2.49 V. It features an initial accuracy of ±1% and a temperature coefficient of 20 ppm/°C. The device supports a maximum shunt current of 10 mA with a dynamic impedance of 0.2 Ω. Designed for surface-mount applications, it utilizes an SOIC-8 narrow package. The operational temperature range spans from 0°C to +70°C, ensuring stable performance in industrial environments.
Feature Summary
- Provides precise 2.5V reference voltage with low temperature drift
- Features ultra-low dynamic impedance for high stability
- Offers adjustable reference voltage via third pin option
- Supports wide operating current range from 400µA to 10mA
Applications
- Precision analog-to-digital converter references
- Portable instrumentation voltage standards
- Battery-powered measurement systems
- Temperature compensated oscillator circuits
Procurement Notes
Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free status and exact electrical tolerances. Ensure the SOIC-8 package dimensions match the PCB footprint requirements. Confirm the operating temperature range aligns with the system's environmental conditions before finalizing procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for precision voltage referencing. The ±1% initial accuracy suits applications demanding tight tolerance without external trimming. Consider the 10mA current limit for load driving capabilities. Compare with LM336M variants if through-hole mounting is preferred or different accuracy grades are needed.
Part Context
Part of the LM336 family of monolithic precision voltage reference diodes. This series includes LM136, LM236, and LM336 variants with varying temperature ranges and accuracies. The BMX suffix indicates a specific tape-and-reel packaging format for automated assembly within the SOIC-8 package line.
Replacement Considerations
LM336BMX-2.5/NOPB is the direct lead-free equivalent. LM336MX-2.5 offers similar specifications in the same package. LM336Z-2.5 provides a through-hole alternative with identical electrical characteristics.
