Product details
Overview
LM4030AMFX4.096/NOPB from Texas Instruments is an ultra-high-precision shunt voltage reference with 4.096 V nominal output, 0.05% initial accuracy (A-grade), 10 ppm/°C temperature coefficient (0°C to +85°C), and SOT-23-5 package. It delivers stable reference voltage for high-resolution ADCs in industrial data acquisition systems requiring <1 LSB error at 12-bit resolution.
For engineers reviewing the LM4030AMFX4.096/NOPB datasheet, LM4030AMFX4.096/NOPB pinout, LM4030AMFX4.096/NOPB application, or LM4030AMFX4.096/NOPB equivalent, this page provides verified electrical parameters, thermal hysteresis (75 ppm), long-term stability (40 ppm), noise performance (165 µVPP, 0.1–10 Hz), and validated alternative options for precision analog signal chains.
Technical Context
The LM4030AMFX4.096/NOPB operates as a two-terminal shunt reference, sinking current from a series resistor to maintain a precise 4.096 V across its VREF and GND terminals. Its dynamic offset cancellation architecture actively compensates for silicon-level mismatches, enabling low thermal hysteresis and immunity to PCB stress effects despite the compact SOT-23-5 footprint.
It functions without mandatory external capacitance but supports up to 10 µF bypass capacitors for improved transient response and broadband noise suppression. Minimum operating current is 130 µA; maximum continuous shunt current is 30 mA, with capability to handle 50 mA transients for <1 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3040AIDBZR | 4.096 V, 0.1% initial accuracy, 50 ppm/°C TC, SOT-23-3, 50 µA min current | Lower accuracy grade; higher tempco; 3-pin package eliminates floating pins but lacks dedicated GND pin | Select when cost sensitivity outweighs 0.05% accuracy requirement and board layout permits shared GND path |
| ADR3440ARJZ-R7 | 4.096 V, 0.1% initial accuracy, 30 ppm/°C TC, SOT-23-5, 120 µA min current | Higher tempco (30 ppm/°C); different pinout (VOUT on Pin 3, GND on Pin 2); no N/C pins | Choose for designs needing same 5-pin footprint but accepting wider thermal drift in non-critical zones |
Compared with REF3040AIDBZR and ADR3440ARJZ-R7, the LM4030AMFX4.096/NOPB offers superior initial accuracy and thermal stability-critical for metrology-grade applications-while its dedicated GND pin (Pin 5) and N/C isolation reduce layout-induced errors in high-EMI environments.

FAQ
What is the guaranteed initial accuracy of the LM4030AMFX4.096/NOPB?
The LM4030AMFX4.096/NOPB is an A-grade device with guaranteed initial accuracy of ±0.05% at 25°C, tested and ensured over the full -40°C to +125°C junction temperature range per TI's SNVS552B datasheet. This corresponds to ±2.05 mV absolute error at 4.096 V output, making it suitable for 12-bit and 13-bit precision systems.
Does the LM4030AMFX4.096/NOPB require an external capacitor to operate?
No, the LM4030AMFX4.096/NOPB is designed for stable operation without any external capacitor. However, a bypass capacitor up to 10 µF may be added between VREF (Pin 4) and GND (Pin 5) to improve transient response and suppress broadband noise-especially beneficial in noisy power-supply environments affecting the LM4030AMFX4.096/NOPB reference node.
What is the minimum operating current for the LM4030AMFX4.096/NOPB?
The LM4030AMFX4.096/NOPB requires a minimum shunt current of 130 µA to maintain regulation at 4.096 V, as specified in the Electrical Characteristics table for the LM4030-4.096 variant. This low current threshold enables use in ultra-low-power applications such as battery-backed sensor nodes where the LM4030AMFX4.096/NOPB remains active during sleep modes.
How does thermal hysteresis impact system calibration when using the LM4030AMFX4.096/NOPB?
Thermal hysteresis for the LM4030AMFX4.096/NOPB is specified at 75 ppm maximum after eight -40°C to +125°C temperature cycles. This translates to ≤0.31 mV shift in the 4.096 V output at 25°C post-cycling-directly limiting recalibration frequency in field-deployed instruments. Systems relying on the LM4030AMFX4.096/NOPB can maintain calibration validity longer than references with >100 ppm hysteresis.
Can the LM4030AMFX4.096/NOPB replace the LM4030BMFX4.096/NOPB in an existing design?
Yes, the LM4030AMFX4.096/NOPB is a direct drop-in replacement for the B-grade LM4030BMFX4.096/NOPB, sharing identical SOT-23-5 (DBV) package, pinout, and operating conditions. The upgrade improves initial accuracy from ±0.10% to ±0.05% and reduces temperature coefficient from 20 ppm/°C to 10 ppm/°C (0°C to +85°C), enhancing overall system precision without layout changes to the LM4030AMFX4.096/NOPB footprint.
