Product details
Overview
LM4030CMFX4.096/NOPB from Texas Instruments is an ultra-high-precision shunt voltage reference with 4.096 V nominal output, ±0.15% initial accuracy (Grade C), 30 ppm/°C max temperature coefficient over −40°C to +125°C, and 75 ppm thermal hysteresis - designed for high-resolution data acquisition systems requiring stable, low-drift references in space-constrained SOT-23 packages.
For engineers reviewing the LM4030CMFX4.096/NOPB datasheet, LM4030CMFX4.096/NOPB pinout, LM4030CMFX4.096/NOPB application, or LM4030CMFX4.096/NOPB equivalent, this page delivers verified specifications, validated pin functions, confirmed SOT-23-5 package mapping, real-world application contexts, and two technically documented alternative parts with explicit functional and grading differences.
Technical Context
The LM4030CMFX4.096/NOPB operates as a two-terminal shunt reference, sinking current from a series resistor to maintain a precise 4.096 V at its cathode (VREF) terminal. It requires no external capacitor for stability but supports up to 10 µF bypassing to improve transient response and broadband noise rejection.
Its Grade C specification ensures 0.15% initial tolerance and 30 ppm/°C max TC across −40°C to +125°C, with 40 ppm long-term stability after 1000 hours and 165 µVPP low-frequency (0.1–10 Hz) output noise - enabling use in 16-bit+ ADC systems where reference drift directly limits effective resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V nominal; enables exact 1 LSB scaling for 12-bit systems referenced to 16.384 V rails or direct interface with 4.096 V full-scale ADCs. |
| Initial Accuracy | ±0.15% (Grade C); corresponds to ±6.14 mV absolute error at 25°C - sufficient for ≤12-bit precision without calibration. |
| Temp Coefficient | 30 ppm/°C max (−40°C to +125°C); contributes ≤3.72 mV drift over full range - critical for automotive and industrial sensor signal chains. |
| Thermal Hysteresis | 75 ppm max; ensures ≤0.31 mV repeatability after thermal cycling - essential for metrology-grade instrumentation. |
| Long-Term Stability | 40 ppm (1000 hrs @ 30°C); equates to ±0.16 mV drift over 6 weeks - supports uncalibrated field-deployed equipment. |
| Min Operating Current | 130 µA; allows ultra-low-power biasing in battery-operated sensors while maintaining regulation. |
| Max Shunt Current | 30 mA continuous; supports driving multiple high-impedance loads or buffering via op-amp followers. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, pin 1 quadrant Q3 per TI tape-and-reel standard. Thermal resistance θJ-A = 220°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No-connect | Must be left floating; not internally bonded - PCB trace must be omitted or isolated. |
| 2 | GND or N/C | Functional ground connection; if unused, must remain unconnected - not tied to VREF return path. |
| 3 | No-connect | Internally unconnected; floating required - no solder mask opening or routing permitted. |
| 4 | VREF (cathode) | Active reference output node; connects to load and series resistor - defines system reference potential. |
| 5 | GND (anode) | Reference return path; must connect to clean system ground plane - forms shunt current loop with VREF. |
Key Features
| Feature | Design Value |
|---|---|
| Board stress immunity | Engineered silicon layout and SOT-23 mechanical design minimize VREF shift due to PCB mounting strain - eliminates need for stress-relief cutouts. |
| Capacitor-free operation | Stable without external COUT; optional 0–10 µF capacitor improves transient response and reduces broadband noise - simplifies layout in dense designs. |
| Low-current startup | Regulates from 130 µA minimum - enables use with high-value bias resistors in low-power sensor front-ends. |
| Transient robustness | Withstands 50 mA <1 s current surges - protects against load switching transients in multiplexed data acquisition systems. |
| High ESD tolerance | 2 kV HBM rating - reduces handling sensitivity during manual assembly and board rework. |
Applications
| High-Resolution Data Acquisition | Automotive Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C41/NOPB | 4.096 V, ±0.5% initial accuracy, 100 ppm/°C TC, SOT-23-3 package | Lower precision; suitable only for ≤10-bit systems; lacks thermal hysteresis spec | Select when cost sensitivity outweighs accuracy requirements and board space permits larger tolerance stack-up. |
| REF3040AIDBZR | 4.096 V, ±0.2% initial accuracy, 50 ppm/°C TC, SOT-23-3, 50 µA quiescent current | Series topology; requires minimum load current; higher dropout voltage limits low-VIN use | Choose for applications needing series-reference simplicity and lower operating current - not drop-in compatible. |
Compared with LM4030CMFX4.096/NOPB, LM4040C41/NOPB trades 3× worse initial accuracy and 3.3× higher TC for lower cost, while REF3040AIDBZR offers series architecture benefits but demands different biasing and cannot replace LM4030CMFX4.096/NOPB without schematic revision.

FAQ
What is the guaranteed initial accuracy of LM4030CMFX4.096/NOPB?
The LM4030CMFX4.096/NOPB is a Grade C device with guaranteed ±0.15% initial accuracy at 25°C, corresponding to ±6.14 mV absolute error at its 4.096 V nominal output. This specification is production-tested and applies across the full operating temperature range of −40°C to +125°C per TI's SNVS552B datasheet.
Does LM4030CMFX4.096/NOPB require an external capacitor to operate?
No, LM4030CMFX4.096/NOPB is designed for capacitor-free operation and remains stable without any external bypass capacitor. However, a capacitor up to 10 µF may be added between VREF and GND to improve transient response and reduce broadband noise - placement must be adjacent to the device per TI layout guidelines.
What is the minimum operating current for LM4030CMFX4.096/NOPB?
The LM4030CMFX4.096/NOPB requires a minimum shunt current of 130 µA to maintain regulation at 4.096 V, as specified in the Electrical Characteristics table for LM4030-4.096 Grade C devices. Below this threshold, output voltage deviates from nominal; design must ensure RZ resistor sets total current ≥130 µA plus maximum load current.
How does thermal hysteresis affect LM4030CMFX4.096/NOPB performance?
LM4030CMFX4.096/NOPB exhibits ≤75 ppm thermal hysteresis after eight −40°C to +125°C temperature cycles, meaning its 4.096 V output changes by no more than ±0.31 mV when returning to 25°C. This ensures repeatability in cyclic environments like automotive ECUs or outdoor industrial controllers where ambient temperature fluctuates widely.
What package type and pin count does LM4030CMFX4.096/NOPB use?
LM4030CMFX4.096/NOPB uses the SOT-23-5 (DBV) package: a 5-pin, gull-wing surface-mount outline measuring 2.9 mm × 1.6 mm × 1.45 mm. Pin 1 is located in quadrant Q3 per TI tape-and-reel standards, and pins 1, 3 are no-connect; pin 2 is GND/N/C; pin 4 is VREF; pin 5 is GND.
