Product details
Overview
LMV118MF from Texas Instruments is a low-voltage, rail-to-rail output operational amplifier with shutdown control, designed for high-speed signal conditioning in space-constrained portable systems. It delivers 45 MHz bandwidth, 40 V/μs slew rate, ±20 mA linear output current, and operates from 2.7 V to 12 V supply - enabling use as a clock buffer, multiplexer driver, or current-sense amplifier in battery-powered instrumentation.
For engineers reviewing the LMV118MF datasheet, LMV118MF pinout, LMV118MF application, or LMV118MF equivalent, this page provides verified specifications, SOT-23-5 pin mapping, real-world multiplexing and low-voltage analog interface use cases, and two validated alternative op-amps with documented functional and supply-current differences.
Technical Context
The LMV118MF uses 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 enable rail-to-rail swing (20 mV from rails) and ±20 mA drive capability while consuming only 600 μA quiescent current.
Shutdown functionality is implemented via an active-high SD pin with 1.95–2.3 V threshold at 2.7 V supply; turnon/turnoff times are 250 ns and 560 ns respectively. In shutdown mode, supply current drops to 15 μA and output enters high-impedance state - critical for low-power multiplexing without signal contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3-dB Bandwidth | 45 MHz - supports clean amplification of clock signals up to ~20 MHz fundamental with minimal phase distortion. |
| Slew Rate | 40 V/μs - enables full-scale 1-V step response in ≤25 ns, suitable for fast transient detection and pulse shaping. |
| Rail-to-Rail Output Swing | 20 mV from rails - preserves >98% dynamic range at 2.7 V supply, essential for ADC front-end buffering. |
| Supply Current (Active) | 600 μA - allows continuous operation in always-on sensor nodes powered by coin cells or energy harvesters. |
| Shutdown Current | 15 μA - reduces system standby power by >97% versus active mode, enabling duty-cycled signal paths. |
| Input Common-Mode Range | −0.3 V to +1.7 V at 2.7 V supply - accepts ground-referenced inputs while operating on single-ended supplies. |
| Output Short-Circuit Current | 32 mA - withstands momentary shorts without latch-up, supporting robust industrial I/O protection. |
Pinout & Package
SOT-23-5 (DBV) package, 2.90 mm × 1.60 mm body size, surface-mount, thermally enhanced layout with exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTPUT | Amplifier output node; high-impedance during shutdown; capable of ±20 mA linear sourcing/sinking. |
| 2 | V− | Negative supply terminal; reference for shutdown logic and input common-mode range; must be tied to GND in single-supply use. |
| 3 | +IN | Non-inverting input; high-impedance (3 MΩ), low bias current (−0.4 μA typical); accepts signals down to −0.3 V. |
| 4 | −IN | Inverting input; matched to +IN for precision closed-loop gain; used with feedback network for stable 2.7–12 V operation. |
| 5 | SD | Shutdown control input; active-high (1.95–2.3 V threshold at 2.7 V); <20 μA input current; requires pull-down to V− for normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Micro-power shutdown | Reduces supply current from 600 μA to 15 μA, enabling time-gated signal acquisition in ultra-low-power systems. |

| Supply-independent bandwidth | Maintains 45 MHz −3-dB BW across 2.7–12 V supply range - eliminates gain-bandwidth trade-offs in multi-rail designs. |
| Low input voltage noise | 40 nV/√Hz at 100 kHz - minimizes added noise in precision transducer amplification and low-level sensor conditioning. |
| Fast shutdown switching | 250 ns turnon / 560 ns turnoff - supports glitch-free 2:1 multiplexing at >1 MHz selection rates without output transients. |
Applications
| High-Speed Clock Buffer | Multiplexed Signal Routing |

IC Role / Device Role / Timing Role: Low-noise, high-bandwidth preamplifier preceding sigma-delta ADC. Use Value: 40 nV/√Hz input voltage noise preserves SNR of microvolt-level sensor signals; 45 MHz BW captures resonant peaks up to 20 MHz. |
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 |
|---|---|---|---|
| LMV721MF | Lower bandwidth (10 MHz), lower supply current (120 μA), no shutdown pin; SOT-23-5 package. | Lacks multiplexing capability; suited for always-on, lower-speed sensing where power is more constrained than speed. | Select when 10 MHz BW suffices and shutdown is unnecessary - reduces BOM count and simplifies control logic. |
| TLV2782IDGKR | Higher supply current (1.3 mA), no shutdown, dual-channel, rail-to-rail I/O; MSOP-8 package. | Requires PCB redesign for dual-channel use; higher quiescent power limits battery life in portable devices. | Choose for dual-amplifier functions (e.g., filter + buffer) where board area permits MSOP-8 and shutdown is not required. |
Compared with LMV721MF and TLV2782IDGKR, the LMV118MF uniquely combines 45 MHz bandwidth, 2.7 V operation, and active-high shutdown in SOT-23-5 - making it the only option among the three for high-speed, low-voltage, power-gated signal routing.

FAQ
What is the shutdown threshold voltage for LMV118MF at 2.7 V supply?
The LMV118MF shutdown pin (SD) has a guaranteed active-high threshold of 1.95 V to 2.3 V when operating at 2.7 V supply. Below 1.95 V, the device remains active; above 2.3 V, it reliably enters shutdown mode with 15 μA supply current. This window ensures robust noise immunity in noisy 2.7 V environments while allowing direct GPIO control from most 3.3 V microcontrollers via level-shifting resistors.
Can LMV118MF operate from a single 2.7 V supply with ground-referenced inputs?
Yes, the LMV118MF supports true single-supply operation at 2.7 V with inputs referenced to ground. Its input common-mode voltage range extends from −0.3 V to +1.7 V, accommodating ground-level signals, and its output swings within 20 mV of both rails - enabling full-scale signal handling without level-shifting circuitry. This makes LMV118MF ideal for interfacing with 2.7 V ADCs and sensors in compact portable designs.
What is the maximum load capacitance LMV118MF can drive while maintaining stability?
The LMV118MF is unity-gain stable and specified to drive ≥100 pF capacitive loads without external compensation, per TI's characterization. For loads exceeding 100 pF (e.g., long traces or multiple inputs), a small series resistor (10–50 Ω) placed adjacent to the OUTPUT pin isolates the capacitive load and preserves phase margin. This behavior is confirmed in Figure 3 (Gain/Phase vs Frequency) of the LMV118MF datasheet under 2.7 V conditions.
Does LMV118MF have ESD protection, and what is its HBM rating?
Yes, the LMV118MF features integrated ESD protection rated at ±2000 V per the Human Body Model (HBM), compliant with ANSI/ESDA/JEDEC JS-001. This level of protection supports safe handling during manual assembly and operation in typical industrial environments without requiring additional external TVS components on signal pins - reducing bill-of-materials cost and PCB area.
How does LMV118MF behave during power-up and shutdown transitions?
The LMV118MF exhibits monotonic, glitch-free behavior during power-up and shutdown: output transitions smoothly without overshoot or ringing, and turnon/turnoff times are tightly specified at 250 ns and 560 ns respectively. During shutdown, the output enters high-impedance state - preventing back-driving of downstream circuitry. These characteristics make LMV118MF suitable for live signal switching in multiplexer applications without requiring external blanking or synchronization logic.
