Product details
Overview
LMV611MG/NOPB from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 5.5 V, delivers 1.4-MHz gain bandwidth, draws only 100 µA supply current per channel, and achieves output swing within 30 mV of rails under 2-kΩ load - enabling precision signal conditioning in battery-powered audio pre-amplifiers and supply current monitoring circuits.
For engineers reviewing the LMV611MG/NOPB datasheet, LMV611MG/NOPB pinout, LMV611MG/NOPB application, or LMV611MG/NOPB equivalent, key selection criteria include its guaranteed 1.8-V operation, −40°C to +125°C temperature range, 4-mV max input offset voltage, rail-to-rail input common-mode range extending 200 mV beyond supplies, and SC70-5 package footprint for space-constrained portable designs.
Technical Context
The LMV611MG/NOPB employs a CMOS input stage enabling rail-to-rail input common-mode voltage (VCM = V− − 0.2 V to V+ + 0.2 V at 25°C) and rail-to-rail output swing (e.g., 1.75 V at V+ = 1.8 V with 2-kΩ load). Its 1.4-MHz unity-gain bandwidth and 0.35 V/µs slew rate support stable AC-coupled amplification up to ~100 kHz at moderate gains.
Designed for single-supply operation down to 1.8 V, it features 100-µA quiescent current per channel, 60-dB minimum CMRR over extended VCM, and 100-dB PSRR - making it suitable for high-impedance sensor interfaces and precision current-sense amplification where supply rejection and input bias current (15 nA typ.) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to Li-ion, coin-cell, or regulated 3.3-V/5-V rails without level shifting. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~140 kHz. |
| Supply Current per Channel | 100 µA typical - allows >10-year battery life in always-on monitoring circuits powered by CR2032 cells. |
| Input Offset Voltage | Max 4 mV - ensures ≤0.4% error in 1-V full-scale current-sense applications without trimming. |
| Output Swing (2-kΩ load) | Within 30 mV of rails at 1.8 V - preserves dynamic range in low-voltage ADC driver stages. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - accepts inputs below ground or above supply, simplifying single-supply transducer interfacing. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin, industrial sensor, and outdoor portable equipment environments. |
Pinout & Package
The LMV611MG/NOPB is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm body), optimized for ultra-compact PCB layouts in handheld and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | Noninverting input | High-impedance CMOS node accepting signals from sensors, DACs, or resistive dividers without loading. |
| 2: V− | Negative supply | Ground reference for single-supply operation; must be connected to system GND or negative rail. |
| 3: −IN | Inverting input | Feedback node for closed-loop configurations; matched to +IN for minimal input offset drift. |
| 4: OUTPUT | Amplifier output | Capable of sourcing/sinking ≥8 mA; drives 600-Ω loads with <105-mV headroom at 1.8 V. |
| 5: V+ | Positive supply | Accepts 1.8–5.5 V; decoupling capacitor (0.1 µF) required adjacent to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8-V supply in single-ended configurations, eliminating need for level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Lower 100-kHz GBW; 6-µA IQ; same SC70-5 package; 2-mV max VOS. | Better suited for sub-10-kHz DC-coupled sensing; insufficient bandwidth for audio pre-amplification. | Select when ultra-low power (<10 µA) dominates over bandwidth and THD performance. |

FAQ
What is the maximum supply voltage for the LMV611MG/NOPB?
The LMV611MG/NOPB supports a maximum supply voltage of 5.5 V across its V+ and V− pins. Absolute maximum ratings specify 6 V differential supply voltage, but operation above 5.5 V risks permanent damage. For reliable long-term use, TI recommends staying within the 1.8 V to 5.5 V recommended operating conditions, especially at elevated temperatures.
Does the LMV611MG/NOPB support true rail-to-rail input and output?
Yes, the LMV611MG/NOPB provides rail-to-rail input common-mode range (V− − 0.2 V to V+ + 0.2 V at 25°C) and rail-to-rail output swing (within 30 mV of rails with 2-kΩ load at 1.8 V). This allows full utilization of low supply voltages in single-supply configurations, such as buffering sensor outputs directly referenced to ground or V+.
What is the typical input offset voltage of the LMV611MG/NOPB?
The LMV611MG/NOPB has a maximum input offset voltage of 4 mV across temperature (−40°C to +125°C), with typical values around 1 mV at 25°C. This specification is ensured for all units in production, enabling predictable DC accuracy in precision gain stages and current-sense applications without external trimming.
Can the LMV611MG/NOPB drive a 600-Ω load effectively?
Yes, the LMV611MG/NOPB can drive a 600-Ω load with output swing within 105 mV of the rails at 1.8 V supply. Its output stage sources up to 8 mA and sinks up to 9 mA, supporting moderate drive requirements in line-driver or ADC-buffer roles while maintaining stability with appropriate compensation.
Is the LMV611MG/NOPB available in packages other than SC70-5?
No - the LMV611MG/NOPB is exclusively offered in the 5-pin SC70 package (2.00 mm × 1.25 mm). The LMV61x family includes dual (LMV612) and quad (LMV614) variants in VSSOP, SOIC, and TSSOP packages, but the single-channel LMV611 is only manufactured in SC70-5 and SOT-23-5 variants; MG/NOPB denotes the SC70 version.
