Product details
Overview
LM4040BIZ-10.0/NOPB from Texas Instruments is a precision micropower shunt voltage reference with 10.0 V nominal reverse breakdown voltage, ±0.2% initial tolerance (B grade) at 25°C, 100 μA minimum operating current, and 100 ppm/°C max temperature coefficient over −40°C to +85°C industrial range. It delivers stable reference voltage in analog input modules and field transmitters where low drift and capacitive-load tolerance are critical.
For engineers reviewing the LM4040BIZ-10.0/NOPB datasheet, LM4040BIZ-10.0/NOPB pinout, LM4040BIZ-10.0/NOPB application, or LM4040BIZ-10.0/NOPB equivalent, this page provides verified specifications, TO-92 package terminal mapping, automotive-grade thermal hysteresis data (0.08%), and direct alternative part comparisons for design-in decisions.
Technical Context
The LM4040BIZ-10.0/NOPB uses Zener-zap trimming during wafer sort to achieve ±0.2% initial accuracy and integrates bandgap-derived curvature correction for low temperature drift. Its dynamic impedance is 0.8 Ω at 1 mA, enabling stable regulation under varying load currents from 100 μA to 15 mA.
Unlike series references, it operates as a two-terminal shunt device requiring only an external current-limiting resistor. It tolerates unlimited capacitive loads without oscillation and requires no output capacitor-simplifying layout in space-constrained industrial and automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.0 V nominal reverse breakdown voltage, specified at 100 μA test current |
| Initial Tolerance | ±0.2% (B grade) at 25°C - translates to ±20 mV absolute error in 10 V output |
| Temp Coefficient | Max 100 ppm/°C over −40°C to +85°C - ensures ≤ ±8.5 mV drift across full industrial range |
| Min Operating Current | 100 μA - sets minimum bias resistor value for reliable turn-on at 10 V output |
| Dynamic Impedance | 0.8 Ω typical at 1 mA - enables <1 mV output change per 1 mA load variation |
| Wideband Noise | 35 μVrms (10 Hz–10 kHz) - supports high-resolution ADC reference applications |
| Thermal Hysteresis | 0.08% - guarantees repeatability after thermal cycling between −40°C and +125°C |
Pinout & Package
LM4040BIZ-10.0/NOPB is packaged in TO-92 (LP package), a 3-pin through-hole plastic case with 4.30 mm × 4.30 mm body size. Pin 1 is Cathode, Pin 2 is Anode, and Pin 3 is NC (no connect, must float or tie to Anode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Pin 1) | Shunt current sink / output node | Connected to regulated 10.0 V node; sinks all excess current from bias resistor |
| Anode (Pin 2) | Reference ground reference | Typically tied to system ground; defines 0 V reference for cathode voltage |
| NC (Pin 3) | No-connect terminal | Must remain unconnected or tied to Anode; improves EMI immunity in noisy environments |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Eliminates BOM cost and board area for stability-enables single-resistor biasing |
| Tolerates capacitive loads | Stable with any output capacitance (e.g., ADC input caps, filtering caps), no phase margin concerns |
| Zener-zap trimmed accuracy | Guaranteed ±0.2% initial tolerance via post-fabrication laser trimming on wafer |
| Low 35 μVrms noise | Supports 16-bit+ SAR and delta-sigma ADCs without added filtering overhead |
| 100 μA min operating current | Enables ultra-low-power operation in battery-backed sensor nodes and energy infrastructure monitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040CIZ-10.0/NOPB | ±0.5% initial tolerance (C grade), same 100 ppm/°C max tempco and TO-92 package | Lower accuracy acceptable in non-critical power supply feedback or coarse sensor biasing | Select when cost sensitivity outweighs need for ±0.2% precision; identical footprint and biasing |
| TL431ACLP | Adjustable 2.5–36 V output via external resistors; 2% initial tolerance; higher 22 Ω dynamic impedance | Used where programmability or higher voltage >10 V is required; not drop-in for fixed 10 V | Choose for flexible output voltage tuning; avoid if fixed 10.0 V, low noise, or low impedance are mandatory |
Compared with LM4040CIZ-10.0/NOPB and TL431ACLP, the LM4040BIZ-10.0/NOPB offers the tightest initial tolerance and lowest dynamic impedance in a fixed 10 V TO-92 package-critical for metrology-grade analog signal chains where gain error and noise directly impact measurement fidelity.

FAQ
What is the minimum operating current for LM4040BIZ-10.0/NOPB?
The LM4040BIZ-10.0/NOPB requires a minimum operating current of 100 μA to maintain regulation at its 10.0 V nominal output. This value is specified across the full industrial temperature range (−40°C to +85°C) and determines the maximum allowable resistance in the bias network. Below 100 μA, the device may exit regulation and exhibit increased output voltage drift.
Does LM4040BIZ-10.0/NOPB require an output capacitor for stability?
No, the LM4040BIZ-10.0/NOPB does not require an output capacitor for stability. Its internal design eliminates the need for external stabilization, and it remains stable with any capacitive load-including ADC input capacitors and bulk filtering caps-without risk of oscillation or phase margin degradation.
What is the temperature coefficient specification for LM4040BIZ-10.0/NOPB?
The LM4040BIZ-10.0/NOPB has a maximum average temperature coefficient of 100 ppm/°C over the industrial temperature range (−40°C to +85°C). This means its output voltage drift is bounded to ±0.85 mV across that range, calculated as 10.0 V × 100 ppm/°C × 85°C span.
Is LM4040BIZ-10.0/NOPB qualified for automotive applications?
Yes, LM4040BIZ-10.0/NOPB is AEC-Q100 Grade 3 qualified (−40°C to +85°C), making it suitable for non-critical automotive applications such as body electronics, battery monitoring, and infotainment power supplies. It is not rated for Grade 1 (−40°C to +125°C) extended automotive use.
What package type is used for LM4040BIZ-10.0/NOPB?
The LM4040BIZ-10.0/NOPB is supplied in a TO-92 (LP) package-a 3-pin through-hole plastic case with 4.30 mm × 4.30 mm body size. Pin 1 is Cathode, Pin 2 is Anode, and Pin 3 is NC (no connect), which must be left floating or tied to the Anode for optimal EMI performance.
