Product details
Overview
LM4030AMF-4.096/NOPB from Texas Instruments is an ultra-high precision shunt voltage reference in SOT-23-5 package, delivering a fixed 4.096 V output with ±0.05% initial accuracy, 10 ppm/°C temperature coefficient (0°C to +85°C), and 75 ppm thermal hysteresis over −40°C to +125°C. It operates continuously at up to 30 mA shunt current and supports high-accuracy data acquisition systems requiring stable, low-drift references.
For engineers reviewing the LM4030AMF-4.096/NOPB datasheet, LM4030AMF-4.096/NOPB pinout, LM4030AMF-4.096/NOPB application, or LM4030AMF-4.096/NOPB equivalent, this page provides verified specifications, validated pin functions, confirmed SOT-23-5 package mapping, real-world application contexts, and two technically documented alternative parts for precision reference design.
Technical Context
The LM4030AMF-4.096/NOPB uses a bandgap-based shunt architecture with dynamic offset cancellation to achieve 0.05% initial tolerance and 10 ppm/°C TC over 0°C–85°C. Its reverse breakdown voltage is specified at 4.096 V with 130 µA minimum operating current and exhibits 15–95 ppm/mA output voltage change versus shunt current.
Designed for operation without external capacitance (though stable with up to 10 µF), it delivers 165 µVPP low-frequency noise (0.1–10 Hz) and maintains immunity to PCB mechanical stress-critical for automotive and industrial instrumentation where long-term drift must remain below 40 ppm over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Initial Accuracy | ±0.05% (A-grade); ensures ≤±2.05 mV absolute error at 25°C for metrology-grade calibration |
| Temp Coefficient | 10 ppm/°C (0°C to +85°C); contributes ≤±0.85 mV drift across industrial ambient range |
| Thermal Hysteresis | 75 ppm max (−40°C to +125°C); limits repeatability error to ≤±0.31 mV after thermal cycling |
| Long-Term Stability | 40 ppm over 1000 hrs; guarantees ≤±0.16 mV output shift during first 6 weeks of field operation |
| Noise (0.1–10 Hz) | 165 µVPP; supports <16-bit ENOB in precision sigma-delta ADC front-ends without additional filtering |
