Product details
Overview
LMV116MFX/NOPB from Texas Instruments is a single-channel, rail-to-rail output voltage-feedback operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 45 MHz bandwidth, 40 V/μs slew rate, ±20 mA linear output current, and 20 mV rail-to-rail output swing at 2.7 V supply - enabling precision buffering in portable clock distribution and transducer interfaces.
For engineers reviewing the LMV116MFX/NOPB datasheet, LMV116MFX/NOPB pinout, LMV116MFX/NOPB application, or LMV116MFX/NOPB equivalent, key selection criteria include its 2.7 V minimum supply operation, microamp-level quiescent current stability across voltage range, rail-to-rail output capability under load, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV116MFX/NOPB employs TI's VIP10 dielectrically isolated bipolar process to sustain 45 MHz −3 dB bandwidth and 40 V/μs slew rate down to 2.7 V supply. Its complementary bipolar input stage and push-pull output stage maintain consistent gain-bandwidth product, output drive, and common-mode rejection (73–88 dB) across 2.7 V to 12 V operation.
Unlike general-purpose op-amps, it features input common-mode voltage range extending to −0.3 V (beyond V−) and output swing within 20 mV of both rails at light loads - critical for maximizing dynamic range in single-supply systems. Input-referred voltage noise is 40 nV/√Hz at 100 kHz, supporting clean amplification of low-level sensor or clock signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 45 MHz - enables stable closed-loop gain up to ~10× at 1 MHz without phase margin erosion. |
| Slew Rate | 40 V/μs - supports distortion-free reproduction of fast-rising edges in clock buffers and pulse amplifiers. |
| Supply Voltage Range | 2.7 V to 12 V - allows direct integration into 3.3 V, 5 V, and dual ±5 V systems without level-shifting. |
| Output Swing | Within 20 mV of either rail - preserves >99% of available voltage headroom in 2.7 V single-supply applications. |
| Supply Current | 600 μA typical - achieves high-speed performance with sub-mA quiescent draw, ideal for battery-powered devices. |
| Input Offset Voltage | ±1 mV (typ), ±5 mV (max) - ensures <0.2% gain error in unity-gain buffer configurations at room temperature. |
| Input Voltage Noise | 40 nV/√Hz at 100 kHz - minimizes added noise in wideband sensor signal chains and RF IF amplification. |
Pinout & Package
SOT-23-5 (DBV) package, 2.90 mm × 1.60 mm body size, surface-mount, moisture-sensitive level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTPUT | Amplifier output node; rail-to-rail capable, ±20 mA linear drive, high-impedance in shutdown (LMV118 only). |
| 2 | V− | Negative supply terminal; accepts ground or negative rail; input common-mode extends 0.3 V below this pin. |
| 3 | +IN | Non-inverting input; high-impedance node (3 MΩ common-mode resistance) for precision reference or sensor inputs. |
| 4 | −IN | Inverting input; matched to +IN for stable feedback networks; supports active filter and transimpedance configurations. |
| 5 | V+ | Positive supply terminal; operates from 2.7 V to 12 V; PSRR ≥72 dB reduces sensitivity to supply ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | 20 mV from either supply rail at light loads - maximizes usable signal range in low-voltage data acquisition. |
| Bandwidth stability vs. supply | 45 MHz maintained from 2.7 V to 12 V - eliminates recalibration when scaling supply for power or noise trade-offs. |
| Low input voltage noise | 40 nV/√Hz at 100 kHz - preserves SNR in front-end amplification of piezoelectric sensors and crystal oscillator buffers. |
| Wide input common-mode range | −0.3 V to +1.7 V (at 2.7 V supply) - accommodates ground-referenced inputs in single-supply systems without level shifters. |
| High PSRR and CMRR | ≥72 dB PSRR, ≥73 dB CMRR - rejects supply noise and common-mode interference in noisy industrial or automotive environments. |
Applications
| High-Speed Clock Buffer/Driver | Current Sense Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | 3 MHz GBW, 1.5 V/μs slew rate, 550 μA supply current - significantly lower speed and drive capability. | Limited to DC–100 kHz signal paths; unsuitable for clock buffering or fast pulse amplification. | Select when ultra-low power (<1 mA) dominates over bandwidth; not a functional replacement for LMV116MFX/NOPB in high-frequency roles. |
| OPA355UA | 200 MHz GBW, 360 V/μs slew rate, 7.5 mA supply current - higher speed but 12× higher quiescent current. | Requires thermal management and larger decoupling; overqualified for 45 MHz needs where power is constrained. | Choose only if system demands >100 MHz bandwidth; otherwise LMV116MFX/NOPB offers optimal speed/power balance. |
Compared with TLV2461IDBVR and OPA355UA, LMV116MFX/NOPB uniquely delivers 45 MHz bandwidth at 600 μA - filling the design gap between micropower op-amps and high-current high-speed alternatives without compromising supply voltage flexibility or rail-to-rail output fidelity.

FAQ
What is the minimum operating supply voltage for LMV116MFX/NOPB?
The LMV116MFX/NOPB operates down to 2.7 V across the full −40°C to +85°C temperature range, with guaranteed specifications including 45 MHz bandwidth and 40 V/μs slew rate. At 2.7 V, output swing remains within 20 mV of both rails and supply current stays at 600 μA typical - making LMV116MFX/NOPB suitable for direct connection to single-cell Li-ion or alkaline battery supplies.
Does LMV116MFX/NOPB support rail-to-rail input operation?
No, LMV116MFX/NOPB does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.3 V to +1.7 V at 2.7 V supply, meaning the inputs must remain at least 0.3 V above V− and no more than 1.7 V above V−. This allows ground-referenced inputs in single-supply systems but excludes direct connection to V+ or V− rails without external level shifting.
What is the output short-circuit current rating for LMV116MFX/NOPB?
The LMV116MFX/NOPB provides ±32 mA short-circuit output current (sinking to V+ and sourcing to V−) under momentary test conditions at 2.7 V supply. Continuous short-circuit operation is limited per absolute maximum ratings: infinite duration below 6 V at room temperature, but only 1.5 ms above 6 V - a safeguard against thermal runaway during fault conditions.
How does LMV116MFX/NOPB compare to LMV118 in pin compatibility and functionality?
LMV116MFX/NOPB is the single-channel, non-shutdown variant in a 5-pin SOT-23 package. LMV118 adds a shutdown (SD) pin, requiring a 6-pin SOT-23. They share identical AC/DC performance specs (bandwidth, slew rate, output drive), but LMV116MFX/NOPB lacks SD functionality and cannot enter low-current shutdown mode - making LMV116MFX/NOPB appropriate for always-on signal paths where simplicity and minimal footprint are priorities.
Is LMV116MFX/NOPB suitable for driving capacitive loads like ADC input capacitors?
Yes, LMV116MFX/NOPB can drive moderate capacitive loads (≤100 pF) directly, as confirmed by stability analysis in TI's application notes. For larger capacitive loads (>100 pF), a small series resistor (10–50 Ω) between LMV116MFX/NOPB output and the capacitor is recommended to isolate the op-amp's output stage and prevent peaking or oscillation - a standard practice validated in LMV11x layout guidelines.
