Product details
Overview
LMH6714MAX from Texas Instruments is a single, unity-gain-stable, current-feedback video operational amplifier in an 8-pin SOIC package. It delivers 400MHz small-signal bandwidth at AV = +2V/V, 1800V/μs slew rate, and 0.01% differential gain / 0.01° differential phase error driving 75Ω video loads - enabling broadcast-quality NTSC/PAL signal conditioning in HDTV distribution systems.
For engineers reviewing the LMH6714MAX datasheet, LMH6714MAX pinout, LMH6714MAX application, or LMH6714MAX equivalent, key selection criteria include its 400MHz bandwidth at 500mVPP output, 0.1dB gain flatness to 120MHz, low 5.6mA supply current, differential gain/phase performance on 150Ω loads, and SOIC-8 thermal resistance of 145°C/W.
Technical Context
The LMH6714MAX employs TI's VIP10 high-speed complementary bipolar process with current-feedback topology, enabling wideband operation independent of closed-loop gain when paired with optimized feedback resistors (e.g., 300Ω for AV = +2). Its input buffer features ~180Ω inverting-input impedance and supports non-inverting gains from +1 to +6V/V and inverting gains from −1 to −5V/V.
It operates from ±4V to ±6.25V supplies (8V–12.5V total), achieves 12ns settling time to 0.05%, and maintains stability with back-terminated 75Ω video loads. The device is not shutdown-capable - that function is exclusive to the LMH6720 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 400MHz at VOUT = 500mVPP - enables full HD baseband video signal amplification without attenuation |
| Slew Rate | 1800V/μs - supports fast transient response for composite sync pulses and digital video edges |
| Differential Gain / Phase | 0.01% / 0.01° at 4.43MHz into 150Ω - meets broadcast-grade NTSC/PAL fidelity requirements |
| Supply Current | 5.6mA typical at ±5V - balances high speed with low power for multi-channel video systems |
| Gain Flatness | 0.1dB from DC to 120MHz - preserves chroma/luma amplitude integrity across video spectrum |
| Output Current | 70mA continuous - drives back-terminated 75Ω loads and multiple video destinations |
| Input Voltage Range | ±2.2V common-mode - accommodates standard video signal swing with headroom |
Pinout & Package
LMH6714MAX is housed in an 8-pin SOIC (Package D), with exposed pad not present. Thermal resistance θJA = 145°C/W. Pinout follows standard op-amp configuration with dual supply rails, differential inputs, and single output.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left unconnected or grounded per layout guidelines |
| 2 | Inverting Input (−IN) | Current-feedback input node; impedance ~180Ω - sets gain with RF and RG |
| 3 | Non-Inverting Input (+IN) | High-impedance voltage input; 2MΩ resistance, 1.0pF capacitance - minimizes loading on source |
| 4 | V− | Negative supply rail - requires local 0.1μF ceramic bypass capacitor to ground |
| 5 | Output | Low-impedance (0.06Ω) buffered output - capable of 70mA drive into 75Ω loads |
| 6 | NC | No internal connection - must be left unconnected or grounded |
| 7 | V+ | Positive supply rail - requires local 0.1μF ceramic bypass capacitor to ground |
| 8 | NC | No internal connection - must be left unconnected or grounded |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables stable wideband operation across gains +1 to +6V/V using fixed RF values - avoids gain-bandwidth trade-off of voltage-feedback amps |
| 0.1dB gain flatness to 120MHz | Preserves relative amplitude of luma/chroma components in SD/HD video - eliminates color distortion in analog transmission |
| 0.01% DG / 0.01° DP at 4.43MHz | Meets SMPTE RP-168 and ITU-R BT.470 broadcast standards for composite video fidelity |
| 1800V/μs slew rate | Accurately reproduces sharp video edges and sync pulses without droop or overshoot |
| Unity-gain stable | Operates reliably at AV = +1 without external compensation - simplifies buffer and cable driver designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum small-signal bandwidth of the LMH6714MAX?
The LMH6714MAX achieves a −3dB small-signal bandwidth of 400MHz at AV = +2V/V with VOUT = 500mVPP into a 100Ω load and ±5V supplies. This bandwidth is validated per the SNOSA39G datasheet Figure 8 and Electrical Characteristics table, and reflects its current-feedback architecture optimized for video applications. Bandwidth reduces to 250MHz at 2VPP output swing due to slew-rate limiting.
Does the LMH6714MAX support shutdown functionality?
No, the LMH6714MAX does not include a shutdown pin or disable function. Shutdown capability is exclusive to the LMH6720 variant (e.g., LMH6720MAX), which adds a TTL-compatible SD pin. The LMH6714MAX is a dedicated high-fidelity video amplifier without power-gating features - its 5.6mA quiescent current remains constant during operation.
What feedback resistor value is recommended for non-inverting gain of +2V/V with the LMH6714MAX?
A 300Ω feedback resistor (RF) is specified in the LMH6714MAX datasheet for AV = +2V/V operation with ±5V supplies and optimal stability, bandwidth, and gain flatness. Using RF = 300Ω with RG = 300Ω yields precise +2V/V gain. Deviating significantly (e.g., RF < 200Ω) risks peaking or oscillation due to current-feedback loop dynamics.
Can the LMH6714MAX drive a 75Ω back-terminated video load?
Yes, the LMH6714MAX is explicitly characterized for 75Ω back-terminated video loads and delivers 0.01% differential gain / 0.01° differential phase at 4.43MHz under those conditions. Its 70mA continuous output current and 0.06Ω closed-loop output impedance ensure stable drive into 75Ω, meeting SMPTE and ITU-R broadcast standards as documented in Figures 1 and 16 of the SNOSA39G datasheet.
What is the thermal resistance (θJA) of the LMH6714MAX package?
LMH6714MAX uses an 8-pin SOIC package (Package D) with a junction-to-ambient thermal resistance (θJA) of 145°C/W, as specified in the Operating Ratings table of the SNOSA39G datasheet. This value assumes standard JEDEC 2S2P test board conditions and informs derating calculations - for example, at 25°C ambient, max power dissipation before reaching 150°C junction is (150−25)/145 ≈ 0.86W.
