Product details
Overview
LMV2011MF from Texas Instruments is a high-precision, rail-to-rail output operational amplifier in a 5-pin SOT-23 package, delivering 35 µV max input offset voltage, 3 MHz gain-bandwidth product, and 4 V/µs slew rate at 2.7–5.25 V supply. It features patented auto-zero architecture with no 1/f noise, 130 dB CMRR, and 120 dB PSRR-designed for transducer signal conditioning in low-voltage, high-accuracy analog front-ends.
For engineers reviewing the LMV2011MF datasheet, LMV2011MF pinout, LMV2011MF application, or LMV2011MF equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for precision instrumentation, thermocouple amplification, strain gauge bridges, and ADC buffer designs.
Technical Context
The LMV2011MF employs continuous auto-zero correction to eliminate input offset drift over time and temperature, achieving 0.015 µV/°C TCVOS and 0.006 µV/month long-term drift. Its architecture avoids chopper-induced mixing products, enabling ultra-low distortion (0.02% THD+N) and clean spectral performance up to 10 MHz.
It operates from 2.7 V to 5.25 V with rail-to-rail output swing (30 mV from rails at 2.7 V), 930 µA supply current, and full functionality across 0°C to 70°C. Input stage uses copper leadframe to suppress thermocouple EMF errors, and requires no external capacitors for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 35 µV max (ensured over temperature); enables ≤5 LSB error in 12-bit ADC systems at G = 100 over 30 years. |
| Gain-Bandwidth Product | 3 MHz typical; supports stable unity-gain and high-gain configurations up to ~300 kHz closed-loop bandwidth. |
| Slew Rate | 4 V/µs typical; ensures 1.4 µs settling to 0.01% for 1 V step-suitable for ≥100 kSPS sampling with 12-bit accuracy. |
| CMRR / PSRR | 130 dB / 120 dB typical; rejects common-mode and supply noise in single-supply sensor interfaces without filtering. |
| Output Swing | Rail-to-rail, 30 mV from rails (2.7 V supply, RL = 10 kΩ); maximizes dynamic range when driving 5 V ADCs. |
| Input Noise | 35 nV/√Hz flat spectrum (no 1/f corner); eliminates integration-time-dependent noise growth in DC-coupled measurements. |
| Supply Current | 930 µA typical per channel; enables precision amplification in battery-powered instrumentation with minimal quiescent load. |
Pinout & Package
LMV2011MF is packaged in a 5-pin SOT-23 (DBV) package with exposed pad not electrically connected. Pin 1 is V+, pin 2 is VIN−, pin 3 is VIN+, pin 4 is V−, and pin 5 is VOUT. No external compensation capacitors required.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply terminal; accepts 2.7–5.25 V; internal regulation supports stable biasing across supply range. |
| 2 | VIN− | Inverting input; picoamp-level input current (≤6 pA IOS); matched impedance critical only near V− rail at high temperature. |
| 3 | VIN+ | Non-inverting input; same input current profile as VIN−; copper leadframe minimizes thermocouple-induced offset at junctions. |
| 4 | V− | Negative supply terminal (ground in single-supply use); defines common-mode range and output swing reference. |
| 5 | VOUT | Amplified output; rail-to-rail capable; drives ≥10 kΩ loads to within 30 mV of rails at 2.7 V; 0.05 Ω output impedance. |
Key Features
| Feature | Design Value |
|---|---|
| No 1/f noise | Flat 35 nV/√Hz voltage noise down to 0.1 Hz-eliminates measurement drift during long-integration data acquisition. |
| Copper leadframe | Nullifies thermocouple EMF between IC leads and PCB copper; reduces thermal offset to <0.0014°C-equivalent error. |
| Auto-zero calibration | Continuous offset correction with 12 ms typical calibration time; avoids chopper artifacts and preserves wideband fidelity. |
| Rail-to-rail output | Swings to within 30 mV of V+ and V− at 2.7 V; delivers full-scale signal to 5 V ADCs without level-shifting circuitry. |
| No external capacitors | Internally compensated for unity-gain stability; removes dielectric absorption and leakage-induced settling delays. |

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, 350 kHz GBW, 160 µA supply current; exhibits chopper artifacts above 10 kHz. | Better for ultra-low-power (<1 µA sleep) but lower bandwidth; unsuitable for >50 kHz signal conditioning due to folding artifacts. | Select OPA333AIDBVR only when supply current <200 µA is mandatory and signal bandwidth <100 kHz. |
| LTC2050CS5#TRMPBF | Zero-drift, 5 µV max VOS, 3 MHz GBW, 1.1 mA supply current; higher noise (60 nV/√Hz), no copper leadframe. | Higher precision offset but greater thermal EMF sensitivity; requires guard traces to mitigate PCB thermocouple effects. | Choose LTC2050CS5#TRMPBF when sub-10 µV VOS is required and thermal gradient control is feasible on PCB layout. |
Compared with OPA333AIDBVR and LTC2050CS5#TRMPBF, the LMV2011MF uniquely combines 35 µV VOS, 3 MHz bandwidth, no 1/f noise, and copper leadframe-making it optimal for high-resolution, wideband, thermally sensitive DC measurements where chopper artifacts or thermocouple errors must be eliminated.

FAQ
What is the maximum operating supply voltage for the LMV2011MF?
The LMV2011MF has an absolute maximum supply voltage of 5.5 V, but its specified operating range is 2.7 V to 5.25 V. Operation at 5.25 V ensures all electrical characteristics-including 35 µV max VOS, 130 dB CMRR, and rail-to-rail output swing-are guaranteed across 0°C to 70°C. Exceeding 5.25 V may compromise long-term reliability and parameter assurance.
Does the LMV2011MF require external compensation components?
No, the LMV2011MF is internally compensated for unity-gain stability and requires no external capacitors. This eliminates dielectric absorption and leakage-related settling delays-enabling full accuracy within microseconds after power-up. The architecture maintains phase margin >60° and gain margin >−14 dB across all loads and supply voltages per the datasheet.
How does the LMV2011MF achieve zero 1/f noise?
The LMV2011MF uses patented continuous auto-zero correction-not chopper stabilization-to cancel input offset without introducing 1/f noise or mixing artifacts. Its input-stage design produces flat 35 nV/√Hz voltage noise from 0.1 Hz to 100 kHz, eliminating the time-dependent drift that plagues conventional amplifiers in long-integration measurements.
What is the output voltage swing specification for the LMV2011MF at 2.7 V supply?
At 2.7 V supply and RL = 10 kΩ, the LMV2011MF delivers rail-to-rail output swing to within 30 mV of both V+ and V− (i.e., 0.030 V to 2.670 V). This is measured with VIN(diff) = ±0.5 V and ensures ≥98% of full-scale range is usable when driving 5 V ADCs in single-supply configurations.
Is the LMV2011MF pin-compatible with other SOT-23 op-amps like the LMV321?
No, the LMV2011MF uses a non-standard 5-pin SOT-23 pinout (V+, VIN−, VIN+, V−, VOUT) distinct from generic single op-amps such as LMV321 (V+, VIN+, VIN−, VOUT, V−). Swapping them requires PCB redesign. The LMV2011MF's pin assignment is optimized for auto-zero architecture and cannot be substituted without verifying layout and decoupling compatibility.
