Product details
Overview
LMH6714MF from Texas Instruments is a single-channel, current-feedback video operational amplifier in a 5-pin SOT-23 package, delivering 400MHz small-signal bandwidth at AV = +2V/V, 1800V/μs slew rate, and 0.01% differential gain error-optimized for NTSC/PAL broadcast-quality video signal conditioning in compact analog front-ends.
For engineers reviewing the LMH6714MF datasheet, LMH6714MF pinout, LMH6714MF application, or LMH6714MF equivalent, this page provides verified technical context, pin-level design meaning, video-specific performance validation, and real-world substitution guidance for high-fidelity analog video signal paths.
Technical Context
The LMH6714MF employs TI's VIP10 complementary bipolar process with current-feedback topology to achieve wideband stability without external compensation. Its transimpedance gain stage enables flat frequency response up to 120MHz (0.1dB gain flatness) and supports unity-gain stable operation across ±4V to ±6.25V supplies.
It features low input bias current (±1µA typical), 3.4nV/√Hz input voltage noise, and 1.2pA/√Hz non-inverting input current noise-enabling high dynamic range in 75Ω back-terminated video systems while maintaining 70mA continuous output drive capability into 100Ω loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 400MHz at 500mVPP output - ensures full NTSC/PAL baseband video spectrum (0–5.5MHz) remains within linear region with margin for harmonics |
| Slew Rate | 1800V/μs - supports fast transient fidelity for composite sync pulses and high-resolution digital video transitions |
| Differential Gain / Phase | 0.01% / 0.01° at 4.43MHz - meets broadcast-grade color fidelity requirements for professional video routing and distribution |
| Supply Current | 5.6mA at ±5V - enables low-power portable video equipment without sacrificing bandwidth or linearity |
| Output Drive | 70mA continuous - sustains 2VPP into 100Ω load with minimal distortion, suitable for driving multiple 75Ω coaxial lines via active splitters |
| Harmonic Distortion | −58dBc HD2 / −70dBc HD3 at 20MHz - preserves signal integrity in multi-channel video mixing and analog-to-digital conversion stages |
| Input Voltage Noise | 3.4nV/√Hz above 1MHz - minimizes added noise floor in high-gain video preamplifier configurations |
Pinout & Package
LMH6714MF is housed in a 5-pin SOT-23 (DBV) package with exposed thermal pad (not electrically connected). This ultra-compact surface-mount outline supports high-density PCB layouts in space-constrained video interface modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive supply rail | Accepts +4V to +6.25V; requires local 0.1μF ceramic bypass to ground for RF stability |
| 2 (−IN) | Inverting input | Current-feedback node; impedance ~180Ω; sensitive to stray capacitance-keep trace short and isolated |
| 3 (+IN) | Non-inverting input | High-impedance voltage input (2MΩ); used for DC-coupled video clamping or reference biasing |
| 4 (V−) | Negative supply rail | Accepts −4V to −6.25V; symmetric dual-supply operation required for full output swing |
| 5 (OUTPUT) | Amplifier output | Capable of 70mA sink/source; designed for 75Ω back-termination to minimize reflections in video transmission |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables gain-independent bandwidth tuning via feedback resistor (RF), allowing stable 400MHz operation at AV = +2 with 300Ω RF |
| 0.1dB gain flatness to 120MHz | Preserves amplitude consistency across entire SD/HD video baseband, critical for chroma/luma separation accuracy |
| Low differential gain/phase error | 0.01% / 0.01° eliminates visible color shift and timing skew in composite video signals under 150Ω loading |
| Unity-gain stable operation | Supports buffer-mode deployment (AV = +1) with 600Ω feedback resistor-ideal for video line drivers and impedance matching |
| High output current drive | 70mA continuous output sustains 2VPP into 100Ω while maintaining <0.1dB flatness to 100MHz-enables active video distribution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6720MF/NOPB.A | 6-pin SOT-23 with TTL-compatible shutdown pin; 250MHz large-signal BW; 0.02% differential gain | Required where power gating or multiplexing of video channels is needed; higher DG error limits PAL/NTSC broadcast use | Select when system-level power sequencing or analog switching functionality is required; not drop-in due to extra shutdown pin and different pinout |
| THS3201DGN | Single 8-pin MSOP; 1.8GHz GBW; 4000V/μs slew; 1.9nV/√Hz noise; no shutdown | Better suited for ultra-wideband test equipment or high-definition serial digital interfaces requiring >1GHz small-signal response | Choose for applications demanding higher speed or lower noise than LMH6714MF; requires layout revision due to different package and biasing |
Compared with LMH6714MF, LMH6720MF offers integrated shutdown but trades 0.01% differential gain accuracy and 400MHz bandwidth for control flexibility, while THS3201DGN delivers superior speed and noise performance at the cost of higher power (12.5mA) and reduced video-specific optimization.

FAQ
What is the maximum recommended feedback resistor value for stable operation of the LMH6714MF?
The LMH6714MF is optimized for 300Ω feedback resistance at AV = +2V/V with ±5V supplies, delivering near-maximal bandwidth and 0.1dB gain flatness. Using 400Ω improves stability with only minor bandwidth reduction, while values below 200Ω risk peaking and oscillation. For unity-gain buffers, a 600Ω feedback resistor is mandatory per TI's application guidelines for the LMH6714MF.
Does the LMH6714MF support single-supply operation?
No, the LMH6714MF requires dual ±4V to ±6.25V supplies for specified performance. Its input common-mode range is ±2.2V and output swing is ±3.4V into 100Ω-both referenced to ground-making true single-supply use incompatible with datasheet specifications. Attempting single-supply operation degrades differential gain/phase, bandwidth, and output linearity beyond guaranteed limits for the LMH6714MF.
Can the LMH6714MF drive a standard 75Ω video load directly?
Yes, the LMH6714MF is explicitly characterized for 75Ω back-terminated loads and achieves 0.01% differential gain/0.01° phase error under those conditions. It delivers 2VPP into 150Ω (two parallel 75Ω loads) with minimal degradation. For optimal performance, use series-source termination at the output and maintain controlled-impedance PCB traces to preserve signal integrity in the LMH6714MF video path.
How does thermal performance of the LMH6714MF compare across package types?
The LMH6714MF in 5-pin SOT-23 (DBV) has a θJA of 232°C/W, significantly higher than the SOIC-8 variant (145°C/W). At 5.6mA quiescent current and ±5V supplies, junction temperature rise exceeds 65°C in still air-requiring careful thermal layout. Use of solder-mask-defined thermal pad area and internal copper planes is strongly advised to manage thermal stress in high-density designs using the LMH6714MF.
Is the LMH6714MF pin-compatible with other devices in the LMH67xx family?
No, the LMH6714MF (5-pin SOT-23) is not pin-compatible with LMH6720MF (6-pin SOT-23, adds shutdown pin) or LMH6722 variants (14-pin SOIC/TSSOP/WSON). Pinouts differ fundamentally: LMH6714MF lacks shutdown functionality and uses dedicated V+ and V− pins, whereas LMH6720MF repurposes Pin 6 as SD. Direct replacement requires PCB redesign; the LMH6714MF must be treated as a distinct footprint in layout for any design targeting its specific video performance envelope.
