Product details
Overview
LM4030BMFX4.096/NOPB from Texas Instruments is an ultra-high precision shunt voltage reference delivering 4.096 V output with ±0.05% initial accuracy, 10 ppm/°C temperature coefficient (0°C to +85°C), and 75 ppm thermal hysteresis across −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 LM4030BMFX4.096/NOPB datasheet, LM4030BMFX4.096/NOPB pinout, LM4030BMFX4.096/NOPB application, or LM4030BMFX4.096/NOPB equivalent, this device serves as a critical precision reference in ADC biasing, sensor signal conditioning, and calibration-critical instrumentation where long-term stability and board-stress immunity are mandatory.
Technical Context
The LM4030BMFX4.096/NOPB implements a bandgap-based shunt architecture optimized for minimal voltage drift over temperature and time. Its dynamic offset cancellation scheme actively compensates for internal mismatches, enabling 40 ppm long-term stability and robust immunity to PCB mechanical stress effects.
Designed for operation without external capacitance, it remains stable with up to 10 µF bypass capacitors and exhibits only 15–95 ppm/mA reverse breakdown voltage change across 160 µA to 30 mA shunt current - a key enabler for load-varying precision systems.

FAQ
What is the minimum operating current for LM4030BMFX4.096/NOPB?
The LM4030BMFX4.096/NOPB requires a minimum shunt current of 130 µA to maintain regulation at 4.096 V. This value is specified at 25°C and ensures stable reference voltage under light-load conditions, making LM4030BMFX4.096/NOPB suitable for ultra-low-power sensor interfaces and energy-harvesting systems where current budget is constrained.
Does LM4030BMFX4.096/NOPB require an external capacitor?
No, LM4030BMFX4.096/NOPB is designed to operate stably without any external capacitor. However, a bypass capacitor up to 10 µF may be added at the VREF pin to improve transient response and reduce broadband noise - particularly beneficial in noisy industrial environments or fast-switching power supply domains where LM4030BMFX4.096/NOPB supplies ADC references.
What does the 'B' grade signify in LM4030BMFX4.096/NOPB?
The 'B' in LM4030BMFX4.096/NOPB denotes the accuracy grade: ±0.10% initial tolerance and 20 ppm/°C temperature coefficient over −40°C to +125°C. This grade balances high precision with cost efficiency for applications demanding better stability than commercial-grade references but not requiring the tightest A-grade specs - such as factory-calibrated industrial transmitters using LM4030BMFX4.096/NOPB.
How is thermal hysteresis specified for LM4030BMFX4.096/NOPB?
LM4030BMFX4.096/NOPB exhibits ≤75 ppm thermal hysteresis, measured as the voltage difference at 25°C before and after eight full thermal cycles from −40°C to +125°C. This specification ensures repeatable reference voltage behavior in systems subject to repeated power cycling or environmental temperature swings - a critical parameter for LM4030BMFX4.096/NOPB in field-deployed instrumentation and automotive ECUs.
Can LM4030BMFX4.096/NOPB be used in place of LM4030AMFX4.096/NOPB?
Yes, LM4030BMFX4.096/NOPB is a functional drop-in alternative to LM4030AMFX4.096/NOPB in most designs, sharing identical SOT-23-5 (DBV) package, pinout, and electrical interface. The primary difference is reduced initial accuracy (±0.10% vs. ±0.05%) and higher temperature coefficient (20 ppm/°C vs. 10 ppm/°C), so LM4030BMFX4.096/NOPB is appropriate where those relaxed specs meet system requirements - e.g., in cost-optimized medical or industrial modules using LM4030BMFX4.096/NOPB.
