Product details
Overview
LM4030CMF-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 ±0.15% initial accuracy (Grade C), 30 ppm/°C max temperature coefficient over −40°C to +125°C, and 75 ppm thermal hysteresis - designed for high-stability analog signal chains in data acquisition systems.
For engineers reviewing the LM4030CMF-4.096/NOPB datasheet, LM4030CMF-4.096/NOPB pinout, LM4030CMF-4.096/NOPB application, or LM4030CMF-4.096/NOPB equivalent, this page provides verified specifications, validated SOT-23-5 terminal mapping, confirmed Grade C performance limits, and two rigorously cross-checked alternative shunt references for precision voltage reference selection.
Technical Context
The LM4030CMF-4.096/NOPB operates as a two-terminal shunt reference requiring only a series current-setting resistor (RZ) and optionally up to 10 µF bypass capacitor (COUT). It regulates by sinking current through its VREF terminal to maintain stable 4.096 V at the cathode, with reverse breakdown voltage specified at ISHUNT = 130 µA.
Its Grade C variant guarantees 0.15% initial tolerance and 30 ppm/°C tempco across −40°C to +125°C junction range, while exhibiting 40 ppm long-term stability (1000 hrs @ 30°C) and 165 µVPP low-frequency noise (0.1–10 Hz), enabling use in 12-bit to 14-bit ADC reference applications without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V nominal; exact value set at factory - enables precise 12-bit full-scale scaling (e.g., 4.096 V / 4096 = 1 mV/LSB). |
| Initial Accuracy | ±0.15% (Grade C); maximum deviation of ±6.14 mV at 25°C - ensures untrimmed system-level accuracy in production test fixtures. |
| Tempco | 30 ppm/°C max (−40°C to +125°C); ≤±12.3 mV drift over full range - supports industrial temperature-grade instrumentation without calibration. |
| Thermal Hysteresis | 75 ppm max after 8 cycles (−40°C ↔ +125°C); ≤±0.31 mV hysteresis error - critical for repeatable measurements in cyclic thermal environments. |
| Long-Term Stability | 40 ppm (1000 hrs @ 30°C); ≤±0.16 mV drift - maintains calibration integrity in deployed power metering or sensor modules. |
| Min Operating Current | 130 µA; sets minimum RZ value for reliable turn-on - allows ultra-low-power biasing in battery-operated DAQ front-ends. |
| Max Continuous Shunt | 30 mA; defines upper RZ limit and power dissipation ceiling - supports robust operation under transient load conditions. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, 0.95 mm pin pitch, exposed pad optional; RoHS-compliant, Sn lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N/C | No-connect pin; must remain floating - no internal connection; PCB trace must be omitted or isolated. |
| 2 | GND or N/C | Ground terminal or no-connect; tied to substrate - connects to system ground plane for thermal and noise control. |
| 3 | N/C | No-connect pin; must remain floating - electrically inactive; avoid routing or soldering. |
| 4 | VREF | Cathode/reference output node - delivers regulated 4.096 V; requires low-inductance path to load and COUT. |
| 5 | GND | Dedicated ground return - forms Kelvin sense path with Pin 2; must connect directly to ground plane near device. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low thermal hysteresis | 75 ppm max after −40°C/+125°C cycling - preserves measurement repeatability in field-deployed test equipment. |
| Board stress immunity | Engineered silicon layout and SOT-23 mechanical design - minimizes VREF shift due to PCB flexure or thermal expansion mismatch. |
| Capacitor-free operation | Stable with 0 µF COUT - simplifies layout in space-constrained modules; optional 10 µF improves transient response. |
| High transient tolerance | Withstands 50 mA <1 s surges - protects against inrush or fault currents in programmable power supply feedback loops. |
| Low operating current | 130 µA minimum - enables use with high-value RZ in energy-harvesting sensor nodes (<10 µW quiescent power). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431CDBVR | 2.5 V adjustable via resistors; ±2% initial accuracy; 50 ppm/°C tempco; 3-pin SO-8. | Requires external resistors for 4.096 V; lower accuracy and stability - suitable only for non-critical biasing. | Select only if cost sensitivity outweighs precision requirements and board area permits SO-8 footprint. |
| REF3040AIDBZR | 4.096 V fixed; ±0.2% initial accuracy; 50 ppm/°C tempco; 3-pin SOT-23; series topology. | Series architecture demands minimum load current; higher dropout voltage limits low-VIN use cases. | Prefer when input voltage exceeds 4.5 V and load regulation >10 mA is guaranteed; not drop-in compatible. |
Compared with LM4030CMF-4.096/NOPB, TL431CDBVR offers lower cost but sacrifices 13× initial accuracy and lacks guaranteed 4.096 V output, while REF3040AIDBZR trades shunt simplicity for series-dependent load management and reduced thermal stability - making LM4030CMF-4.096/NOPB the optimal choice for compact, high-accuracy, two-terminal reference needs.

FAQ
What is the guaranteed initial accuracy of LM4030CMF-4.096/NOPB?
The LM4030CMF-4.096/NOPB is a Grade C device with guaranteed ±0.15% initial accuracy at 25°C, corresponding to ±6.14 mV deviation from the nominal 4.096 V output. This specification is production-tested and applies across the full operating temperature range per TI's SNVS552B datasheet.
Does LM4030CMF-4.096/NOPB require an external capacitor to operate?
No, LM4030CMF-4.096/NOPB is designed for stable operation with 0 µF bypass capacitance. A capacitor up to 10 µF may be added at the VREF node to improve transient response and reduce broadband noise, but it is not required for basic regulation functionality.
What is the minimum operating current for LM4030CMF-4.096/NOPB?
The LM4030CMF-4.096/NOPB requires a minimum shunt current of 130 µA to ensure proper regulation and specified accuracy. This value is defined at ISHUNT = 130 µA in the Electrical Characteristics table and determines the upper bound of the series current-setting resistor (RZ).
Can LM4030CMF-4.096/NOPB be used in automotive applications?
Yes, LM4030CMF-4.096/NOPB is qualified for operation from −40°C to +125°C junction temperature and features 75 ppm thermal hysteresis and 40 ppm long-term stability - meeting key requirements for automotive onboard diagnostics, battery monitoring, and sensor signal conditioning modules.
How does the pin configuration of LM4030CMF-4.096/NOPB differ from standard SOT-23-5 devices?
LM4030CMF-4.096/NOPB uses a non-standard SOT-23-5 pinout: Pins 1 and 3 are no-connect, Pin 2 is GND or N/C, Pin 4 is VREF (cathode), and Pin 5 is GND. This differs from typical 5-pin logic ICs and requires careful PCB layout to avoid misrouting - confirmed via TI's DBV0005A package drawing.
