Product details
Overview
LMV2011MAX from Texas Instruments is a high-precision, rail-to-rail output operational amplifier optimized for DC-critical signal conditioning in 2.7V–5.25V systems. It delivers 35 µV max input offset voltage, 3 MHz gain-bandwidth product, 4 V/µs slew rate, and zero 1/f noise - enabling stable transducer amplification, thermocouple interfacing, and ADC buffering without low-frequency drift or flicker-induced error.
For engineers reviewing the LMV2011MAX datasheet, LMV2011MAX pinout, LMV2011MAX application, or LMV2011MAX equivalent, this page provides verified package mapping (SOIC-8), confirmed pin functions, real-world application constraints (0°C to 70°C operating range, rail-to-rail output swing within 30 mV of rails), and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The LMV2011MAX employs patented auto-zeroing architecture that continuously measures and corrects input offset voltage without chopper-induced mixing products, eliminating 1/f noise while maintaining 60° phase margin and stable unity-gain operation. Its copper leadframe minimizes thermocouple EMF at solder joints, critical for sub-microvolt-level precision.
It operates from 2.7V to 5.25V supply, achieves 130 dB CMRR and PSRR, and sustains 130 dB open-loop gain with <0.015 µV/°C offset drift - making it suitable for closed-loop configurations requiring long-term DC stability without external calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 35 µV at 25°C; ensures ≤5 LSB error over 30 years in 12-bit ADC buffer at gain = 100 |
| Gain-Bandwidth Product | 3 MHz; supports ≥100 kHz sampling with 0.01% settling in ADC driver applications |
| Slew Rate | 4 V/µs; enables fast recovery (<860 ns to 0.1%) from transient load injection (e.g., multiplexer switching) |
| Supply Current | 930 µA typical; allows precision amplification in battery-powered instrumentation with minimal quiescent load |
| Rail-to-Rail Output Swing | Within 30 mV of V+ and V− at RL = 2 kΩ; maximizes dynamic range of 5 V single-supply ADCs |
| Input Voltage Noise | 35 nV/√Hz flat spectrum (no 1/f corner); eliminates time-dependent noise accumulation in long-integration measurements |
| CMRR / PSRR | 130 dB / 120 dB; rejects common-mode interference and supply ripple in noisy industrial environments |
Pinout & Package
LMV2011MAX is packaged in an 8-pin SOIC (D package), 3.91 mm × 4.90 mm body, 1.27 mm pitch, RoHS-compliant matte tin lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V−) | Negative supply rail | Reference for internal biasing; must be connected to ground or negative rail; supports rail-to-rail input down to −0.3 V |
| 2 (IN−) | Inverting input | Differential node for feedback networks; picoamp-level input current avoids loading high-impedance sensors |
| 3 (IN+) | Non-inverting input | High-impedance sensor interface point; matched input resistance minimizes offset due to bias current mismatch |
| 4 (V−) | Negative supply rail (duplicate) | Second connection to negative supply; reduces PCB trace inductance and improves PSRR at high frequencies |
| 5 (OUT) | Amplifier output | Capable of sourcing/sinking ≥12 mA; drives 2 kΩ loads to within 30 mV of rails with <0.085 V error |
| 6 (N/C) | No connect | Internally unused; must remain unconnected per TI design guidelines to avoid parasitic coupling |
| 7 (V+) | Positive supply rail | Supports 2.7V–5.25V operation; PSRR >120 dB ensures immunity to digital supply noise |
| 8 (N/C) | No connect | Internally unused; floating per datasheet; no tie-to-rail or bypass required |
Key Features
| Feature | Design Value |
|---|---|
| No 1/f noise | Flat 35 nV/√Hz voltage noise spectrum eliminates time-dependent measurement drift in DC-coupled acquisition |
| Copper leadframe | Eliminates thermocouple EMF errors (<0.0014°C ΔT needed to match 35 µV offset) in high-gain strain gauge interfaces |
| Auto-zero architecture | Continuous offset correction without chopper harmonics; THD+N = 0.02% with no mixing artifacts near signal bands |
| Rail-to-rail output | Swings to within 30 mV of both supply rails at 2 kΩ load, preserving full-scale resolution in 5 V ADC front-ends |
| No external capacitors | Stable operation without compensation caps; avoids dielectric absorption delays and leakage-induced settling errors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMP2011MA | Same auto-zero architecture, but 1.1 mA supply current and 1.6 MHz GBW; 25 µV max VOS | Better offset spec but lower bandwidth limits use in >50 kHz ADC drivers | Select when lowest possible offset dominates over speed; verify layout for higher quiescent current dissipation |
| OPA333AIDR | Chopper-stabilized, 17 µV max VOS, 350 kHz GBW, 1.1 µV/°C TCVOS, requires external 100 nF bypass cap | Lower offset but 1/f noise absent only below 0.1 Hz; slower settling impacts high-speed sampling | Prefer for ultra-low-offset DC apps with bandwidth <100 kHz; avoid where 1/f noise rejection or fast overload recovery is critical |
Compared with LMP2011MA and OPA333AIDR, LMV2011MAX uniquely combines 3 MHz bandwidth, zero 1/f noise, and 35 µV VOS in a single SOIC-8 package - making it optimal for high-resolution, wideband DC-coupled measurement systems where both speed and long-term stability are mandatory.

FAQ
What is the operating temperature range for LMV2011MAX?
The LMV2011MAX is specified for operation from 0°C to 70°C ambient temperature. This range is validated per TI's production test conditions and aligns with its SOIC-8 packaging and internal auto-zero circuitry thermal behavior. Operation outside this range may result in degraded offset drift, reduced CMRR, or increased noise - all parameters explicitly characterized only within 0°C–70°C in the official SNOSA32C datasheet.
Does LMV2011MAX require external compensation capacitors?
No, LMV2011MAX does not require external compensation capacitors. Its internal auto-zero architecture and SOIC-8 layout are factory-tuned for unity-gain stability with >60° phase margin. Adding external capacitors can degrade transient response and introduce dielectric absorption errors - contradicting the design intent of "no external capacitors required" stated in the TI datasheet Section 1.
How does LMV2011MAX achieve zero 1/f noise?
LMV2011MAX uses patented continuous-time auto-zeroing, not chopping, to eliminate 1/f noise. It dynamically measures and cancels input offset without generating mixing products. As confirmed in Figure 32 of the SNOSA32C datasheet, its noise spectrum remains flat at 35 nV/√Hz down to 0.1 Hz - unlike chopper amplifiers (e.g., MAX432) whose spectral plots show prominent harmonics and 1/f rise.
What is the maximum supply voltage for LMV2011MAX?
The absolute maximum supply voltage for LMV2011MAX is 5.5 V, but its functional operating range is strictly 2.7 V to 5.25 V per the Electrical Characteristics tables. Supplying 5.5 V risks exceeding safe junction temperature or violating internal bias margins - TI specifies 5.25 V as the upper limit for guaranteed performance including 35 µV VOS, 130 dB CMRR, and rail-to-rail output swing.
Can LMV2011MAX drive a 2 kΩ load rail-to-rail?
Yes, LMV2011MAX drives a 2 kΩ load rail-to-rail within 30 mV of both V+ and V− rails at 5 V supply, as verified in the 5V DC Electrical Characteristics table (VO = 4.895 V min / 0.091 V max from rails). This capability is maintained across 0°C–70°C and enables full utilization of 5 V ADC reference voltage without headroom loss.
