Product details
Overview
LMV651MF/NOPB from Texas Instruments is a single-channel, rail-to-rail output, low-voltage operational amplifier optimized for battery-powered and space-constrained systems. It delivers 12 MHz unity-gain bandwidth with only 116 μA supply current at 5 V, 1.5 mV max input offset voltage, and 17 nV/√Hz input voltage noise - enabling precision signal conditioning in portable instrumentation and automotive sensor interfaces.
For engineers reviewing the LMV651MF/NOPB datasheet, LMV651MF/NOPB pinout, LMV651MF/NOPB application, or LMV651MF/NOPB equivalent, key selection criteria include its 2.7–5.5 V supply range, −40°C to 125°C operation, SC70-5/SOT-23-5 package compatibility, and verified stability with ≤100 pF capacitive loads without external compensation.
Technical Context
The LMV651MF/NOPB employs TI's VIP50 process to achieve high bandwidth-per-power efficiency: its 12 MHz gain-bandwidth product is sustained at just 116 μA quiescent current. The amplifier features a ground-sensing input stage (common-mode range includes V−) and rail-to-rail output swing (within 120 mV of rails at 2 kΩ load), supporting true single-supply operation down to 2.7 V.
It exhibits 100 dB CMRR and 95 dB PSRR across 2.7–5.5 V supplies, with 0.003% THD+N at 1 kHz into 2 kΩ. Stability is guaranteed for unity-gain configurations with ≤100 pF capacitive load; larger loads require external RC compensation per Figure 35 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion (3.0–4.2 V) and 3.3 V/5 V logic systems without level-shifting. |
| Unity-Gain Bandwidth | 12 MHz - supports audio-band amplification, anti-aliasing filtering, and fast sensor signal conditioning up to ~1 MHz closed-loop. |
| Quiescent Current | 116 μA at 5 V - allows >1-year battery life in always-on sensor nodes powered by CR2032 or coin cells. |
| Input Offset Voltage | Max ±1.5 mV - ensures <0.3% gain error in 100× transimpedance amplifiers used with photodiodes or strain gauges. |

Pinout & Package
LMV651MF/NOPB is packaged in a 5-pin SC70 (2.00 mm × 1.25 mm) or SOT-23 (2.90 mm × 1.60 mm) surface-mount outline. Both variants share identical pinout and thermal performance (RθJA = 303.5°C/W for SC70, 214.2°C/W for SOT-23).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | Noninverting Input | Accepts DC-coupled signals down to V− (ground in single-supply); common-mode range extends to negative rail. |
| 2: V− | Negative Supply | Reference node for single-supply operation (typically GND); must be low-impedance for PSRR integrity. |
| 3: −IN | Inverting Input | Used for inverting gain stages, active filters, and current-to-voltage conversion; matched to +IN for CMRR. |
| 4: OUT | Amplifier Output | Rail-to-rail capable; drives 2 kΩ loads within 120 mV of supply rails; not short-circuit protected. |
| 5: V+ | Positive Supply | Accepts 2.7–5.5 V; decoupling capacitor (0.1 μF ceramic) required within 2 mm for stability and PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full supply voltage swing (e.g., 0–4.88 V on 5 V rail), maximizing dynamic range for ADC drivers and reference buffers. |
| Ground-sensing input | Common-mode input range includes V−, enabling direct interface with 0 V-referenced sensors (e.g., bridge-based pressure transducers). |
| 12 MHz bandwidth at 116 μA | Best-in-class 103 kHz/μA bandwidth-to-power ratio - outperforms comparable micropower op-amps by >3× in speed-efficiency tradeoff. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6741IDBVR | Higher 10 MHz GBW, 125 μA IQ, 0.5 mV VOS max, but only rated to 125°C (not 125°C continuous operation like LMV651MF/NOPB). | Better offset for precision DC sensing; less suitable for wideband AC-coupled audio due to lower GBW. | Select TLV6741IDBVR when <0.5 mV offset is mandatory and bandwidth ≤10 MHz suffices. |
| OPA316IDBVR | 10 MHz GBW, 400 μA IQ, 0.15 mV VOS max, 11 nV/√Hz noise, but consumes >3× more current than LMV651MF/NOPB. | Superior noise and offset for high-accuracy instrumentation; incompatible with multi-year battery life requirements. | Choose OPA316IDBVR only when ultra-low noise (<12 nV/√Hz) and sub-0.2 mV offset outweigh power budget constraints. |
Compared with TLV6741IDBVR and OPA316IDBVR, LMV651MF/NOPB uniquely balances 12 MHz bandwidth, 116 μA quiescent current, and 125°C operation - making it the optimal choice for long-life, high-temperature, wideband sensor interfaces where power and thermal robustness are co-primary constraints.

FAQ
What supply voltage range does the LMV651MF/NOPB support?
The LMV651MF/NOPB operates from 2.7 V to 5.5 V, making it compatible with single-cell Li-ion (3.0–4.2 V), 3.3 V logic rails, and legacy 5 V systems. Its performance is fully specified at both 3 V and 5 V, with guaranteed functionality across the entire range - including startup at 2.7 V and thermal stability up to 125°C.
Is the LMV651MF/NOPB unity-gain stable?
Yes, the LMV651MF/NOPB is unity-gain stable and characterized for stable operation with closed-loop gains ≥1. It maintains ≥45° phase margin with ≤100 pF capacitive load at the output; larger loads require external compensation per Figure 35 in the LMV651 datasheet (SNOSAI7K).
What is the maximum output swing of the LMV651MF/NOPB?
At 5 V supply and 2 kΩ load, the LMV651MF/NOPB delivers output swing within 120 mV of each rail (i.e., 0.12 V to 4.88 V). At lighter 10 kΩ loads, swing improves to within 60 mV of rails. This rail-to-rail capability maximizes dynamic range for ADC interfacing and reference buffering.
Does the LMV651MF/NOPB have rail-to-rail input capability?
No - the LMV651MF/NOPB has rail-to-rail *output* but only ground-sensing *input*: its common-mode input range extends to V− (including 0 V in single-supply use) but stops 1.2 V below V+. This enables direct interface with ground-referenced sensors while maintaining high CMRR across the usable input range.
What package options are available for the LMV651MF/NOPB?
The LMV651MF/NOPB is offered in two industry-standard 5-pin packages: SC70 (2.00 mm × 1.25 mm) and SOT-23 (2.90 mm × 1.60 mm). Both share identical pinout, electrical specs, and thermal characteristics - allowing drop-in layout reuse between compact (SC70) and hand-solderable (SOT-23) variants.
