Overview
The LM4040AIZ-10.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 10.0 V with an initial accuracy of ±0.1%. The device operates within an industrial temperature range of -40°C to +125°C and features a maximum temperature coefficient of 70 ppm/°C. It utilizes a TO-92 package for through-hole mounting and requires a minimum operating current of 10 µA at 25°C.
Feature Summary
- Provides high precision with ±0.1% initial accuracy at 25°C
- Operates with ultra-low power consumption suitable for battery applications
- Maintains stability across the full industrial temperature range
- Capable of driving capacitive loads without oscillation
Applications
- Portable instrumentation requiring stable reference voltages
- Battery-powered measurement systems
- Data acquisition systems
- Precision analog circuits
Procurement Notes
Verify that the component is sourced from authorized distributors to ensure authenticity. Confirm the specific suffix matches the required tolerance and package type. Check for RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability records for quality assurance purposes.
Selection Notes
Select this component when a fixed 10V reference with high precision is required in a through-hole configuration. Consider the low operating current for power-sensitive designs. Verify that the thermal performance meets the application's environmental requirements within the specified temperature range.
Part Context
This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed output voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V. The 'A' designation indicates the highest accuracy tier of ±0.1%, while the 'I' denotes the industrial temperature range. The 'NOPB' suffix signifies lead-free packaging compliant with environmental standards.
Replacement Considerations
LM4040AIZ-10.0/NOPB is functionally equivalent to other LM4040AIZ-10.0 variants. Cross-reference with LM4040AIM3X-10.0/NOPB for surface-mount alternatives if PCB layout changes are permitted.
