Product details
Overview
LMV116MFX from Texas Instruments is a single-channel, rail-to-rail output voltage-feedback operational amplifier optimized for low-voltage, high-speed applications. 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 signal conditioning in portable instrumentation and clock buffering circuits.
For engineers reviewing the LMV116MFX datasheet, LMV116MFX pinout, LMV116MFX application, or LMV116MFX equivalent, key selection criteria include its micro-power operation (600 μA supply current), input common-mode range extending to −0.3 V, 40 nV/√Hz input voltage noise at 100 kHz, and compatibility with 2.7–12 V single-supply or ±1.35–±6 V dual-supply configurations.
Technical Context
The LMV116MFX employs TI's VIP10 dielectrically isolated bipolar process, enabling 45 MHz −3 dB bandwidth and 40 V/μs slew rate even at 2.7 V supply. Its complementary bipolar input stage and push-pull output stage maintain stable gain, bandwidth, and output drive across 2.7–12 V supply range.
No shutdown functionality is integrated - unlike the LMV118 variant - making the LMV116MFX a dedicated high-speed amplifier without enable control. Input common-mode voltage spans −0.3 V to 1.7 V (at 2.7 V supply), and output swings within 20 mV of either rail under light load, supporting wide dynamic range in low-voltage systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV721M5X | Lower bandwidth (10 MHz), higher input bias current (1.2 μA), same SOT-23-5 package and 2.7 V min supply. | Not suitable for >10 MHz clock buffering or fast transient capture; better for DC-coupled sensor amps with lower speed requirements. | Select LMV721M5X only if bandwidth <10 MHz suffices and cost sensitivity outweighs speed needs. |
| OPA355DBVR | Higher bandwidth (200 MHz), higher supply current (6.5 mA), same rail-to-rail output but narrower input CMVR (−0.1 V to V+−1.2 V). | Requires ≥3 V supply and careful input biasing; unsuitable for −0.3 V input or ultra-low-power designs. | Choose OPA355DBVR only when >100 MHz bandwidth is mandatory and power budget allows 10× higher IS. |
Compared with LMV721M5X and OPA355DBVR, the LMV116MFX uniquely balances 45 MHz bandwidth, 600 μA supply current, and −0.3 V input common-mode capability - making it optimal for 2.7 V portable systems needing speed, precision, and ground-referenced input support without trade-offs in power or voltage range.

FAQ
What is the minimum supply voltage for reliable operation of the LMV116MFX?
The LMV116MFX is specified for continuous operation down to 2.7 V supply voltage, with full performance including 45 MHz bandwidth, 40 V/μs slew rate, and rail-to-rail output swing validated at this level. Operation below 2.5 V is not guaranteed per datasheet Absolute Maximum Ratings and may result in degraded gain, bandwidth, or output drive capability. The LMV116MFX must be operated within 2.7–12 V for compliant performance.
Does the LMV116MFX include a shutdown pin?
No, the LMV116MFX does not include a shutdown pin. Shutdown functionality is exclusive to the LMV118 variant (pin 5 = SD). The LMV116MFX is a 5-pin SOT-23 device with fixed operation on pins 1 (OUTPUT), 2 (V−), 3 (+IN), 4 (−IN), and 5 (V+). Any attempt to force shutdown via external circuitry will not disable internal biasing and may cause undefined behavior or damage.
What is the input common-mode voltage range of the LMV116MFX at 2.7 V supply?
At 2.7 V supply, the LMV116MFX supports an input common-mode voltage range of −0.3 V to 1.7 V, as specified in the Electrical Characteristics table for 2.7 V operation. This allows direct interfacing with ground-referenced sources and accommodates inputs below the negative rail - critical for current-sense and single-supply transducer applications. Performance degrades outside this range, with CMRR falling below 50 dB.
Can the LMV116MFX drive a 50 Ω load directly?
The LMV116MFX can source/sink ±20 mA continuously, supporting a minimum load resistance of 125 Ω at full rail-to-rail swing (2.7 V ÷ 20 mA = 135 Ω). Driving a 50 Ω load requires 54 mA peak current - exceeding the ±20 mA linear output rating. Sustained 50 Ω loading risks thermal overload, output clipping, or reliability degradation. For 50 Ω line driving, use an external buffer or select a higher-output-current amplifier such as the OPA2350.
What package type is used for the LMV116MFX?
The LMV116MFX is supplied in a 5-pin SOT-23 (DBV) package with nominal body dimensions of 2.90 mm × 1.60 mm. This RoHS-compliant, surface-mount package supports automated assembly and meets JEDEC moisture sensitivity level 1 (MSL-1) requirements. Pin configuration matches industry-standard SOT-23 footprints, with pin 1 = OUTPUT, pin 2 = V−, pin 3 = +IN, pin 4 = −IN, and pin 5 = V+.
