Product details
Overview
LMV611MF/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 product, draws only 100 µA supply current per channel, and achieves output swing within 30 mV of rails with 2-kΩ load - enabling precision signal conditioning in battery-powered audio pre-amplifiers and supply current monitoring circuits.
For engineers reviewing the LMV611MF/NOPB datasheet, LMV611MF/NOPB pinout, LMV611MF/NOPB application, or LMV611MF/NOPB equivalent, key selection criteria include its 1.8-V minimum supply capability, −40°C to +125°C operating temperature range, 4-mV maximum input offset voltage, rail-to-rail common-mode input extending 200 mV beyond supplies, and SC70-5 packaging for space-constrained PCB layouts.
Technical Context
The LMV611MF/NOPB employs a CMOS input stage enabling ultra-low input bias current (15 nA typical) and rail-to-rail input common-mode range (V– – 0.2 V to V+ + 0.2 V at 25°C). Its internal architecture supports stable unity-gain operation with 67° phase margin and 7 dB gain margin at 1.8 V.
It delivers consistent 1.4-MHz gain-bandwidth across 1.8 V–5.5 V supply range and maintains 80 dB CMRR over 0 V ≤ VCM ≤ 0.6 V and 1.4 V ≤ VCM ≤ 1.8 V at 1.8 V supply - critical for accurate sensing in single-supply systems where input signals approach supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct integration into 2-cell alkaline, Li-ion, or regulated 3.3-V systems without level-shifting. |
| Gain-Bandwidth Product | 1.4 MHz - supports stable amplification of audio-band signals (up to ~100 kHz closed-loop) with minimal phase error. |
| Supply Current per Channel | 100 µA typical - extends battery life in portable equipment; 185 µA max ensures predictable power budgeting. |
| Input Offset Voltage | 4 mV maximum - limits DC error in precision sensor interfaces and current-sense amplifiers at room temperature. |
| Output Swing (2-kΩ load) | Within 30 mV of each rail at 1.8 V - preserves dynamic range in low-voltage ADC driver and comparator input stages. |
| Input Common-Mode Range | V– – 0.2 V to V+ + 0.2 V at 25°C - allows direct connection to ground-referenced sensors or DAC outputs in single-supply configurations. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin, industrial control, and extended-environment portable electronics. |
Pinout & Package
The LMV611MF/NOPB is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm body size), optimized for high-density PCB layouts in portable and battery-powered devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | Noninverting input | High-impedance CMOS node accepting signals down to V– – 0.2 V; used for positive feedback or reference input in buffer/amp configurations. |
| 2: V– | Negative supply | Ground or negative rail connection; must be decoupled locally to suppress noise coupling into sensitive input stage. |
| 3: –IN | Inverting input | High-impedance CMOS node; forms feedback path in transimpedance or inverting amplifier topologies. |
| 4: OUTPUT | Amplifier output | Rail-to-rail capable output driving up to 2-kΩ load within 30 mV of rails; requires series resistor if driving capacitive loads >100 pF. |
| 5: V+ | Positive supply | Primary power input (1.8–5.5 V); local 0.1-µF ceramic decoupling capacitor required between Pin 5 and Pin 2 for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of supply voltage headroom in single-supply systems - critical for maximizing SNR in 1.8-V ADC drivers. |
| 100-µA quiescent current | Reduces system-level power consumption by >50% versus comparable 1-MHz op amps, extending runtime in coin-cell or energy-harvesting applications. |
| 200-mV beyond-rail input common-mode | Supports direct interfacing to sensors or DACs whose outputs exceed supply rails - eliminates need for external level-shifting circuitry. |
| 1.4-MHz GBW at 1.8 V | Maintains usable bandwidth even at minimum supply voltage - unlike many low-power op amps that degrade GBW below 2.7 V. |
| −40°C to +125°C operation | Validated performance across automotive under-hood and industrial ambient conditions without derating or thermal management overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6001IDBVR | Lower 70-µA supply current but reduced 0.5-MHz GBW; 3-mV max VOS. | Better for ultra-low-power <100-kHz sensor buffering; insufficient for audio pre-amplification requiring >1-MHz bandwidth. | Select TLV6001IDBVR when power budget is tighter than bandwidth requirement and VOS sensitivity is higher than GBW. |
| OPA316IDBVR | Higher 100-µA supply current, 10-MHz GBW, 0.5-mV max VOS, and 1.2-pA input bias current. | Preferred for precision, higher-speed applications like active filters or fast-settling data acquisition - at cost of 7× higher quiescent power. | Select OPA316IDBVR when VOS and speed dominate design constraints, and 10-MHz bandwidth justifies increased power draw. |
Compared with TLV6001IDBVR and OPA316IDBVR, LMV611MF/NOPB uniquely balances 1.4-MHz bandwidth, 100-µA supply current, and 4-mV VOS in SC70-5 - making it optimal for cost-sensitive, battery-powered systems needing moderate speed and rail-to-rail operation without premium precision.

FAQ
What is the minimum supply voltage supported by the LMV611MF/NOPB?
The LMV611MF/NOPB operates down to 1.8 V, making it suitable for direct use with two-cell alkaline, NiMH, or single-cell Li-ion battery systems without regulation. This 1.8-V minimum is guaranteed across the full −40°C to +125°C temperature range and is validated in TI's production testing per the SNOSC69D datasheet revision March 2017.
Does the LMV611MF/NOPB support rail-to-rail input and output simultaneously?
Yes, the LMV611MF/NOPB supports 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 each rail with 2-kΩ load at 1.8 V). This dual rail-to-rail capability enables true single-supply operation in applications such as battery voltage monitoring and sensor signal conditioning where both input and output must utilize full supply headroom.
What is the maximum input offset voltage specification for LMV611MF/NOPB?
The LMV611MF/NOPB has a maximum input offset voltage of 4 mV at 25°C, as specified in Section 6.5 of the SNOSC69D datasheet. This value applies to the LMV611 (single-channel variant) and is tested across the recommended operating conditions - ensuring predictable DC accuracy in precision amplification and current-sense applications without trimming.
Which package does the LMV611MF/NOPB use, and what are its dimensions?
The LMV611MF/NOPB uses the SC70-5 package with nominal body dimensions of 2.00 mm × 1.25 mm, as confirmed in the Device Information table on page 2 of the SNOSC69D datasheet. This ultra-small outline package provides the smallest footprint among LMV61x variants and is pin-compatible with the SOT-23-5 variant (2.92 mm × 1.60 mm), though mechanical layout differs.
Can the LMV611MF/NOPB drive a 600-Ω load effectively?
Yes, the LMV611MF/NOPB can drive a 600-Ω load with output swing within 80 mV of each rail at 1.8 V supply, as specified in the "Output Swing" parameter under Electrical Characteristics – 1.8 V (DC). It delivers ±8 mA short-circuit output current, supporting moderate drive strength while maintaining stability - verified in TI's application note SNAA217 for low-power op amp load driving.
