Overview
The LM4040BIZ-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 2.5V output with ±0.1% initial accuracy. It operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 40 ppm/°C. The device supports a maximum cathode current of 15mA and requires a minimum operating current of 65µA. Packaged in a compact TO-92 (TO-226AA) three-pin format, it is designed for surface or through-hole mounting.
Feature Summary
- Provides high-precision fixed voltage reference with ±0.1% initial accuracy
- Features ultra-low temperature coefficient of 40 ppm/°C for thermal stability
- Operates with micropower consumption requiring only 65µA minimum current
- Supports up to 15mA load current in a standard three-terminal package
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Digital-to-analog converter (DAC) voltage references
- Battery-powered measurement instrumentation
- Portable test equipment calibration circuits
Procurement Notes
Verify the specific suffix 'B' confirms the ±0.1% accuracy grade and 'I' indicates the industrial temperature range (-40°C to +85°C). Ensure the 'NOPB' designation matches lead-free and RoHS compliance requirements for your assembly process. Confirm the TO-92 package variant aligns with your PCB footprint specifications before ordering.
Selection Notes
Select this component when circuit design demands tight voltage tolerance and minimal drift over temperature variations. The low quiescent current makes it suitable for battery-operated systems where power efficiency is critical. Compare against higher accuracy grades if tighter tolerances are required, or lower grades if cost reduction is prioritized over precision performance.
Part Context
This part belongs to the LM4040-N series of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades, including ±0.1%, ±0.2%, and ±1%. The LM4040BIZ-2.5/NOPB specifically targets applications requiring the highest precision within the industrial temperature range using a traditional through-hole compatible package.
Replacement Considerations
LM4040AIM3-2.5/NOPB: Higher automotive qualification grade with extended temperature range. LM4040BIM3-2.5/NOPB: Same electrical specifications but in SOT-23 surface-mount package.
