Product details
Overview
LMV2011MFX/NOPB from Texas Instruments is a high-precision, rail-to-rail output operational amplifier in 5-pin SOT-23 package, featuring 35 µV max input offset voltage (over temperature), 35 nV/√Hz flat-band voltage noise with no 1/f component, 130 dB CMRR, 3 MHz gain-bandwidth product, and 4 V/µs slew rate. It delivers ultra-stable DC accuracy for transducer signal conditioning in low-voltage (2.7–5.25 V) industrial and instrumentation systems.
For engineers reviewing the LMV2011MFX/NOPB datasheet, LMV2011MFX/NOPB pinout, LMV2011MFX/NOPB application, or LMV2011MFX/NOPB equivalent, key selection criteria include guaranteed low VOS drift (0.015 µV/°C), copper leadframe for thermocouple cancellation, no external capacitors required, and fast overload recovery (≤50 ms) - critical for precision ADC buffering and strain-gauge amplification.
Technical Context
The LMV2011MFX/NOPB employs patented auto-zeroing architecture that continuously measures and corrects input offset without chopper-induced mixing products, enabling true 1/f-noise-free operation. Its input stage uses matched MOSFET pairs on a copper leadframe to eliminate thermoelectric EMFs at PCB solder joints.
This architecture delivers 0.02% THD+N at 1 kHz and supports stable unity-gain and high-gain configurations up to AV = 1000 while maintaining ≥60° phase margin across 2.7–5.25 V supply range and −40°C to +85°C extended operation (per characterization data).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 35 µV over full operating temperature (0°C to 70°C); ensures ≤0.5 LSB error in 12-bit ADC buffer at G = 100 |
| Voltage Noise Density | 35 nV/√Hz (flat, no 1/f corner); eliminates measurement drift in long-integration applications like weigh scales |
| CMRR / PSRR | 130 dB / 120 dB; rejects common-mode interference from noisy digital supplies or sensor cabling |
| Rail-to-Rail Output Swing | 30 mV from rails (at RL = 10 kΩ, VS = 5 V); maximizes dynamic range of single-supply 5 V ADCs |
| Supply Current | 930 µA typical; enables precision amplification in battery-powered portable instrumentation |
| Gain-Bandwidth Product | 3 MHz; supports stable closed-loop gains up to 1000 with ≥60° phase margin |
| Overload Recovery Time | ≤50 ms (to 0.1%); recovers faster than chopper-stabilized op-amps after saturation, critical for multiplexed sensor arrays |
Pinout & Package
LMV2011MFX/NOPB is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is V+, Pin 2 is VIN−, Pin 3 is VIN+, Pin 4 is V−, Pin 5 is VOUT. No NC pins are internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive supply input | Accepts 2.7–5.25 V; internal regulation enables stable bias under supply ripple |
| 2 (VIN−) | Inverting input | Differential pair gate node; picoamp-level input current minimizes resistor-induced offset errors |
| 3 (VIN+) | Non-inverting input | Matched to VIN−; copper leadframe eliminates thermocouple voltage at PCB interface |
| 4 (V−) | Negative supply input / ground reference | Supports single-supply operation down to 0 V; common-mode range extends to −0.3 V |
| 5 (VOUT) | Amplified output | Rail-to-rail swing with <0.05 Ω output impedance; drives 2 kΩ loads without gain loss |
Key Features
| Feature | Design Value |
|---|---|
| No 1/f voltage noise | Flat 35 nV/√Hz spectral density from 0.1 Hz to 100 kHz eliminates integration-time-dependent drift in precision DC measurements |
| Copper leadframe | Eliminates thermocouple EMFs (<0.0014°C ΔT required for 35 µV error), critical for µV-level strain-gauge and thermocouple amplifiers |
| Auto-zero without chopping artifacts | No mixing products near signal band; THD+N = 0.02% at 1 kHz avoids harmonic distortion in sensor front-ends |
| No external capacitors required | Internal stability compensation removes dielectric absorption delays, enabling sub-millisecond turn-on settling |
| Fast overload recovery | ≤50 ms recovery from 2× full-scale overdrive enables use in multiplexed sensor systems with rapid channel switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Chopper-stabilized; 10 µV max VOS but exhibits 1/f noise corner at ~0.1 Hz and 250 ms overload recovery | Higher initial accuracy but unsuitable for long-integration or rapidly multiplexed sensors | Select LMV2011MFX/NOPB when 1/f-noise elimination and fast recovery outweigh lowest initial VOS |

FAQ
What is the maximum guaranteed input offset voltage for LMV2011MFX/NOPB over temperature?
The LMV2011MFX/NOPB has a maximum input offset voltage of 35 µV over the full operating temperature range of 0°C to 70°C, as specified in the 5V DC Electrical Characteristics table. This value is ensured by production testing and applies to all units shipped in this variant. The LMV2011MFX/NOPB achieves this stability through continuous auto-zero correction and copper leadframe construction, making it suitable for applications demanding long-term DC accuracy without recalibration.
Does LMV2011MFX/NOPB require external compensation capacitors?
No, the LMV2011MFX/NOPB does not require external capacitors for stability. Its internal compensation network ensures unity-gain stability across the full 2.7–5.25 V supply range and temperature span. This eliminates dielectric absorption and leakage-related settling delays, enabling sub-millisecond turn-on readiness - a key advantage over alternatives like LTC2050 that mandate external capacitance. The LMV2011MFX/NOPB's capacitor-free design simplifies layout and improves reliability in high-humidity or long-life deployments.
How does the copper leadframe in LMV2011MFX/NOPB improve measurement accuracy?
The copper leadframe in the LMV2011MFX/NOPB eliminates thermocouple EMFs generated at solder joints between dissimilar metals (e.g., Kovar leads and copper PCB traces). Conventional packages can produce >35 µV/°C error from minute temperature gradients; the LMV2011MFX/NOPB's matched copper construction cancels this effect, reducing thermally induced offset to negligible levels. This is critical in µV-level applications like strain-gauge bridges and thermocouple amplifiers, where even 0.0014°C ΔT would otherwise corrupt readings - directly enhancing accuracy in the LMV2011MFX/NOPB's target use cases.
What is the typical supply current consumption of LMV2011MFX/NOPB?
The LMV2011MFX/NOPB consumes 930 µA typical supply current at 5 V and 25°C, with a maximum of 1.5 mA across temperature and supply voltage. This low quiescent current enables use in battery-powered portable instrumentation and energy-conscious industrial sensors. The LMV2011MFX/NOPB maintains full precision performance (including 35 µV VOS and 130 dB CMRR) at this current level, distinguishing it from higher-power zero-drift amplifiers - making it ideal for always-on or duty-cycled precision signal chains where power budget is constrained.
Can LMV2011MFX/NOPB drive a 2 kΩ load while maintaining rail-to-rail output swing?
Yes, the LMV2011MFX/NOPB delivers rail-to-rail output swing into a 2 kΩ load: at VS = 5 V, it swings within 91–140 mV of each rail (VOUT = 0.091–4.919 V), per the 5V DC Electrical Characteristics table. Its 0.05 Ω output impedance ensures minimal gain error under load. This capability allows direct interfacing with medium-impedance ADC inputs or downstream buffers without external level-shifting circuitry - a verified design feature of the LMV2011MFX/NOPB that supports full dynamic range utilization in single-supply 5 V systems.
