Overview
The LM4030AMF-4.096/NOPB is an ultra-high precision shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of 0.05% and a temperature coefficient of 30 PPM/C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 50 mA. It is housed in a compact SOT-23-5 surface-mount package, designed for applications requiring stable reference voltages under varying thermal conditions.
Feature Summary
- Ultra-high precision performance with 0.05% initial accuracy
- Low temperature drift characterized at 30 PPM/C
- Robust operation across extended industrial temperature ranges
Applications
- Precision data acquisition systems
- Battery-powered instrumentation
- High-resolution analog-to-digital converter references
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the 'AM' grade corresponds to the 0.05% accuracy specification required for your design. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when strict accuracy and low thermal drift are critical. The 4.096 V output aligns well with standard ADC input ranges. Consider the 50 mA max shunt current limit against your circuit's bias requirements to ensure stable regulation without exceeding power dissipation limits in the small SOT-23-5 package.
Part Context
This part belongs to the LM4030 family of ultra-high precision shunt voltage references from Texas Instruments. It serves as a high-performance alternative to lower-precision variants like the LM4040, offering superior accuracy and stability. The series is widely used in industrial and automotive applications where reliable voltage referencing is essential for signal integrity.
Replacement Considerations
Direct pin-compatible substitutes within the same family include LM4030AIMF-4.096/NOPB. Verify that any replacement maintains the 30 PPM/C temperature coefficient and 0.05% initial accuracy specifications to ensure circuit compatibility.
