Product details
Overview
LMV771MGX/NOPB 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/NOPB datasheet, LMV771MGX/NOPB pinout, LMV771MGX/NOPB application, or LMV771MGX/NOPB equivalent, key selection criteria include guaranteed 2.7V–5.5V operation, −40°C to 125°C temperature range, rail-to-rail output swing into 600 Ω loads, and ultra-low input bias current (100 pA typical) for high-impedance sensor front-ends.
Technical Context
The LMV771MGX/NOPB employs a CMOS input stage with precision trimming to achieve low VOS and sub-1 µV/°C drift, supporting stable DC-coupled amplification across automotive and industrial temperature extremes. Its rail-to-rail output stage uses complementary push-pull architecture to deliver 50 mV from each rail into 2 kΩ and 100 mV into 600 Ω at 2.7V supply.
Designed for low-voltage, low-power systems, the amplifier features 550 µA supply current per channel and maintains 100 dB open-loop gain (RL = 2 kΩ), enabling accurate closed-loop configurations in active filters, current-sense buffers, and precision gain stages without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into Li-ion and dual-cell alkaline systems without LDO regulation. |
| Input Offset Voltage (max) | 0.85 mV at 25°C - enables ≤0.1% error in 100 mV full-scale transducer outputs without trimming. |
| Gain-Bandwidth Product | 3.5 MHz - allows stable unity-gain buffer or 10× inverting amplifier up to 350 kHz with phase margin ≥79°. |
| Voltage Noise Density | 7.5 nV/√Hz at 10 kHz - preserves SNR in audio-band and data-acquisition front-ends with bandwidths <100 kHz. |
| Rail-to-Rail Output Swing | 50 mV from rails into 2 kΩ at 2.7 V - delivers >96% of supply range for ADC driver applications with 12-bit+ resolution. |
| Input Bias Current (typ) | 100 pA - minimizes voltage error across 10 MΩ source impedances (e.g., piezoelectric sensors, pH electrodes). |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments without derating. |
Pinout & Package
LMV771MGX/NOPB is housed in a 5-pin SC70 package (2.0 mm × 1.25 mm, 0.65 mm pitch), optimized for space-constrained portable and automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified signal node; drives capacitive loads ≤100 pF directly; requires series resistor for >100 pF. |
| 2 (−IN) | Inverting Input | Differential input terminal; high-impedance CMOS node (100 pA bias); sensitive to layout-induced leakage. |
| 3 (GND) | Ground Reference | Analog ground return path; must connect to low-impedance ground plane adjacent to IC for noise immunity. |
| 4 (+IN) | Non-Inverting Input | Differential input terminal; matched to −IN for common-mode rejection; avoid floating connections. |
| 5 (V+) | Positive Supply | Single-supply rail; accepts 2.7–5.5 V; bypass with 0.1 µF ceramic capacitor placed ≤2 mm from pin. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Higher 1.5 mV max VOS, lower 1 MHz GBW, same SC70-5 package and 2.7–5.5 V range. | Less suitable for sub-0.5% DC accuracy requirements; adequate for general-purpose buffering. | Select when cost sensitivity outweighs offset and bandwidth needs; verify layout for 100 pA IB vs. MCP6001's 100 nA. |
| TSV911ICT | Lower 1.3 mV max VOS, higher 8 MHz GBW, same rail-to-rail I/O, but SOT23-5 package (slightly larger footprint). | Better for higher-frequency active filters; less optimal for ultra-low-power (<600 µA) designs due to 850 µA IQ. | Choose for bandwidth-critical applications where 200 µA higher quiescent current is acceptable. |
Compared with MCP6001T-E/OT and TSV911ICT, LMV771MGX/NOPB offers the lowest guaranteed offset voltage and best noise-performance trade-off in SC70-5, making it optimal for precision DC-coupled measurement chains where supply current is constrained below 600 µA.

FAQ
What is the maximum input offset voltage specification for LMV771MGX/NOPB over temperature?
The LMV771MGX/NOPB has a maximum input offset voltage of 0.85 mV at 25°C. Over the full −40°C to +125°C operating range, the datasheet specifies 1.0 mV max for the LMV771 variant. This limit ensures predictable DC error in automotive and industrial applications without recalibration.
Does LMV771MGX/NOPB support rail-to-rail input common-mode voltage?
No, LMV771MGX/NOPB does not support rail-to-rail input. Its input common-mode voltage range is specified as 0 V to V+ − 0.9 V, meaning the upper limit is 0.9 V below the positive supply rail. At 2.7 V supply, this allows up to 1.8 V input common-mode; at 5 V, up to 4.1 V.
Can LMV771MGX/NOPB drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, LMV771MGX/NOPB guarantees rail-to-rail output swing into 600 Ω loads: within 100 mV of each rail at 2.7 V supply and within 150 mV at 5 V supply. This capability is validated across −40°C to +125°C and enables direct interfacing with legacy 600 Ω audio or test equipment inputs.
What is the recommended power supply bypassing for LMV771MGX/NOPB?
TI recommends a 0.1 µF ceramic capacitor placed within 2 mm of the V+ (Pin 5) and GND (Pin 3) pins of LMV771MGX/NOPB. For noisy environments, add a 1–10 µF tantalum or aluminum electrolytic capacitor in parallel on the board's main supply rail to suppress low-frequency ripple.
Is LMV771MGX/NOPB qualified for automotive applications?
LMV771MGX/NOPB itself is not AEC-Q100 qualified; that qualification applies only to the LMV772Q variant in the same family. However, LMV771MGX/NOPB shares the −40°C to +125°C operating temperature range and robust construction, making it suitable for non-safety-critical automotive subsystems such as cabin sensors and infotainment analog front-ends.
