Overview
The LM4040DIZ-5.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 5.0 V with an initial accuracy of ±1%. The device operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 150 ppm/°C. It utilizes a TO-92-3 package for through-hole mounting. Key electrical specifications include a maximum shunt current of 15 mA and a typical operating current of 10 µA at 25°C.
Feature Summary
- Provides stable reference voltage over the industrial temperature range
- Ultra-low operating current suitable for power-restricted designs
- Capable of driving capacitive loads while maintaining stability
Applications
- Portable instrumentation requiring low power consumption
- Battery-powered measurement systems
- Data acquisition systems needing precise voltage references
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 manufacturer designation aligns with current Texas Instruments product lines following the acquisition of National Semiconductor assets.
Selection Notes
Select this component when a fixed 5V reference with ±1% accuracy is required in a through-hole TO-92 package. Consider the 150 ppm/°C temperature coefficient for applications where high precision across wide temperature variations is not critical. Evaluate the 15 mA maximum shunt current against load requirements to ensure adequate drive capability without exceeding limits.
Part Context
This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various output voltages and accuracy grades, including A (0.1%), B (0.2%), C (0.5%), and D (1%). The 'NOPB' suffix indicates lead-free packaging compliant with environmental standards. The device is designed for general-purpose voltage referencing in space-constrained or battery-operated applications.
Replacement Considerations
LM4040DIZ-5.0 is a direct functional equivalent. LM4040BIZ-5.0/NOPB offers higher accuracy (0.2%) in the same package. LM4040DIM3X-5.0/NOPB provides surface mount SOT-23-3 compatibility.
