Product details
Overview
LMV771MGX from Texas Instruments is a single-channel, rail-to-rail output, low-noise precision operational amplifier in SC70-5 package. It delivers 850 µV max input offset voltage (25°C), 3.5 MHz gain-bandwidth product, and 7.5 nV/√Hz voltage noise at 10 kHz - enabling high-accuracy signal conditioning in battery-powered instrumentation and transducer interfaces.
For engineers reviewing the LMV771MGX datasheet, LMV771MGX pinout, LMV771MGX application, or LMV771MGX equivalent, key selection criteria include guaranteed 2.7V–5.5V operation, −40°C to +125°C temperature range, rail-to-rail output swing into 2 kΩ loads (≤50 mV from rails), and ultra-low input bias current (100 pA typical) for high-impedance sensor front-ends.
Technical Context
The LMV771MGX employs a CMOS input stage with precision trimming to achieve low offset and drift (−0.45 µV/°C typical), while its rail-to-rail output stage uses complementary push-pull architecture to sustain full-swing performance into heavy loads. Its 3.5 MHz GBW and 1.4 V/µs slew rate support stable unity-gain buffering and active filtering up to ~300 kHz.
Designed for low-voltage precision systems, it operates down to 2.7V with input common-mode range extending to ground (0 V) and up to V+ − 0.9 V, and features 100 dB open-loop gain (RL = 2 kΩ) and 80 dB CMRR over 0.5–1.2 V common-mode range - critical for DC-coupled differential sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Input Offset Voltage (max) | 850 µV at 25°C - enables sub-millivolt DC accuracy in current-sense and bridge amplifier applications. |
| Gain-Bandwidth Product | 3.5 MHz - allows stable unity-gain configuration and supports 10-bit+ data acquisition sampling up to 300 kSPS. |
| Voltage Noise Density | 7.5 nV/√Hz at 10 kHz - minimizes broadband noise contribution in audio and sensor signal chains. |
| Supply Current per Amplifier | 550 µA typical - enables multi-channel, always-on monitoring in portable devices with <1.7 mW power at 3.3 V. |
| Rail-to-Rail Output Swing | ≤50 mV from rails into 2 kΩ - preserves dynamic range in low-voltage ADC drivers and single-supply active filters. |
| Input Bias Current | 100 pA typical at 25°C - prevents significant voltage error across >10 MΩ source impedances (e.g., piezoelectric sensors). |
Pinout & Package
LMV771MGX is housed in a 5-pin SC70 package (2.0 mm × 1.25 mm, 0.65 mm pitch), optimized for space-constrained PCB layouts. Thermal resistance θJA = 440 °C/W reflects its small footprint and low-power operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting Input | High-impedance node (100 pA bias) for feedback networks and differential configurations. |
| 2 - IN+ | Non-Inverting Input | CMOS input referenced to ground or mid-supply; accepts 0 V to V+ − 0.9 V common-mode range. |
| 3 - V− | Negative Supply / Ground | Connects to system ground (single-supply) or negative rail; supports true ground-referenced inputs. |
| 4 - OUT | Amplifier Output | Capable of sourcing/sinking ≥11 mA; drives 600 Ω loads with ≤112 mV headroom at 2.7 V. |
| 5 - V+ | Positive Supply | Accepts 2.7–5.5 V; PSRR ≥76 dB ensures immunity to supply ripple in noisy embedded environments. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C max drift vs. LMV771MGX's −0.45 µV/°C typical; higher 350 µA supply current. | Better long-term DC stability in calibration-critical lab instruments; less suitable for wide-temp automotive due to 125°C max rating. | Select OPA333AIDBVR when sub-µV drift over time is mandatory; LMV771MGX preferred for cost-sensitive, high-temp industrial designs. |
| MCP6V01T-E/OT | Chopper-stabilized; 25 µV max VOS; 1.2 µA supply current; SC70-5 package identical to LMV771MGX. | Lower noise (11.5 nV/√Hz) but higher current draw limits battery life; chopper ripple may affect sensitive analog inputs. | Choose MCP6V01T-E/OT for ultra-low offset in medical sensors; LMV771MGX offers better noise/power trade-off for general-purpose portable electronics. |
Compared with OPA333AIDBVR and MCP6V01T-E/OT, LMV771MGX provides the optimal balance of low noise, low power, and extended temperature capability in SC70-5 - making it ideal for automotive and industrial signal chains where cost, size, and thermal robustness are prioritized over zero-drift performance.

FAQ
What is the maximum input offset voltage specification for LMV771MGX over temperature?
The LMV771MGX has a maximum input offset voltage of 850 µV at 25°C. Over the full operating range of −40°C to +125°C, the datasheet guarantees ≤1.0 mV for the LMV771 variant. This limit ensures predictable DC accuracy in automotive and industrial environments where thermal cycling occurs.
Does LMV771MGX support rail-to-rail input common-mode voltage?
No, LMV771MGX does not support rail-to-rail input. Its input common-mode voltage range is specified from 0 V to V+ − 0.9 V. At 2.7 V supply, this permits operation from ground up to +1.8 V - sufficient for ground-referenced sensors but not for signals near V+.
Can LMV771MGX drive a 600 Ω load at 2.7 V supply?
Yes, LMV771MGX can drive a 600 Ω load at 2.7 V supply, delivering output swing within 100 mV of each rail (i.e., 0.1 V to 2.6 V). The datasheet specifies this performance with RL = 600 Ω and VO = 0.2 V to 2.5 V, confirming usability in legacy line-driver and video-buffer applications.
What is the thermal resistance (θJA) of the LMV771MGX SC70-5 package?
The LMV771MGX in SC70-5 package has a junction-to-ambient thermal resistance (θJA) of 440 °C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions and informs derating calculations for continuous operation at elevated ambient temperatures.
Is LMV771MGX qualified for automotive applications?
No - only the LMV772Q variant is AEC-Q100 Grade 1 qualified. The LMV771MGX shares the same −40°C to +125°C operating range and robust construction, but lacks formal automotive qualification documentation and stress-test validation required for safety-critical vehicle subsystems.
