Product details
Overview
LMH6715MA from Texas Instruments is a dual wideband current-feedback operational amplifier optimized for broadcast-quality video signal processing. It delivers 400MHz small-signal bandwidth at AV = +2V/V, 1300V/μs slew rate, and 0.02% differential gain error driving 75Ω video loads - enabling high-density NTSC/PAL/HDTV distribution systems with minimal signal degradation.
For engineers reviewing the LMH6715MA datasheet, LMH6715MA pinout, LMH6715MA application, or LMH6715MA equivalent, this page provides verified technical context, exact SOIC-8 pin mapping, real-world video and IQ channel use cases, and two validated alternative op amps with documented performance trade-offs.
Technical Context
The LMH6715MA implements TI's VIP10 complementary bipolar process with current-feedback topology, delivering inherently high slew rate and gain-bandwidth independence from closed-loop gain setting. Its matched dual amplifiers share a monolithic die, ensuring tight AC/DC tracking across channels - critical for differential line drivers and Sallen-Key active filters.
Each amplifier features ±2.2V common-mode input range, ±3.9V output swing into 100Ω at ±5V supplies, and −70dB input-referred crosstalk at 10MHz. The device is unity-gain stable and requires precise feedback resistor (RF) selection - 500Ω recommended for AV = +2 - to balance bandwidth, flatness, and stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 400MHz at AV = +2V/V, RL = 100Ω - supports full HD baseband video without attenuation up to 100MHz (0.1dB flatness). |
| Slew Rate | 1300V/μs - enables clean 2V step response with 12ns settling to 0.05%, essential for fast-switching video routing. |
| Differential Gain/Phase Error | 0.02% / 0.02° at 4.43MHz into 150Ω - meets broadcast-grade NTSC/PAL fidelity requirements for multi-load distribution. |
| Channel Crosstalk | −70dB at 10MHz - ensures isolation between dual channels in IQ amplifiers and differential receivers. |
| Supply Current per Channel | 5.8mA typical at ±5V - enables dual-channel high-speed operation within 11.6mA total, suitable for power-constrained portable RF designs. |
| Input Voltage Noise | 3.4nV/√Hz >1MHz - preserves SNR in wideband active filters and transimpedance amplifiers up to 100MHz. |
| Output Current Drive | 70mA - drives four back-terminated 75Ω video loads simultaneously without gain compression or distortion. |
Pinout & Package
LMH6715MA is housed in an 8-pin SOIC (D) package with 1.27mm pitch, 3.91mm body width, and 1.75mm max height - compatible with standard surface-mount assembly and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch1) | Current-feedback node; requires low-parasitic layout and precise RF placement to maintain stability and bandwidth. |
| 2 | Non-Inverting Input (Ch1) | High-impedance input (1MΩ); common-mode range ±2.2V - must stay within rails to avoid saturation. |
| 3 | Output (Ch1) | Class A/B output capable of ±3.9V into 100Ω; series Rs recommended for capacitive loads to optimize settling time. |
| 4 | VEE (−5V) | Negative supply pin; requires local 0.1μF ceramic + bulk tantalum decoupling placed <2mm from pin. |
| 5 | VCC (+5V) | Positive supply pin; decoupling identical to VEE; shared supply lines must be isolated per channel to minimize crosstalk. |
| 6 | Output (Ch2) | Electrically matched to Pin 3; layout symmetry critical for differential applications like single-to-differential conversion. |
| 7 | Non-Inverting Input (Ch2) | Matched to Pin 2; DC offset drift ±30μV/°C - enables precision DC-coupled instrumentation amplifier topologies. |
| 8 | Inverting Input (Ch2) | Matched to Pin 1; RF value directly sets bandwidth and stability - 300Ω–500Ω typical for AV = +2 applications. |
Key Features
| Feature | Design Value |
|---|---|
| Dual monolithic matching | AC/DC parameters tightly tracked across channels - enables true differential signaling without external trimming. |
| Current-feedback architecture | Bandwidth remains stable across gains; RF adjustment (not gain-setting resistors) controls frequency response. |
| Video-optimized distortion performance | HD2 = −60dBc and HD3 = −75dBc at 20MHz - preserves chroma/luma integrity in HDTV switching matrices. |
| Low-noise input stage | 3.4nV/√Hz voltage noise + 1.4pA/√Hz non-inverting current noise - ideal for low-level signal conditioning in RF IQ paths. |
| Unity-gain stability | No external compensation required; operates reliably at AV = +1V/V with proper RF selection (≥500Ω). |
Applications
| NTSC/PAL Video Distribution | HDTV Line Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual wideband op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6720MA | Higher 720MHz bandwidth at AV = +2, but 7.5mA/channel supply current and no guaranteed 0.02% video specs. | Better for RF IF amplification; less validated for broadcast video compliance testing. | Select when >500MHz bandwidth is mandatory and video differential gain/phase certification is not required. |
| THS3202D | Lower 400MHz bandwidth but superior 1.8nV/√Hz noise and −85dBc HD3 at 20MHz; SOIC-8 pinout identical. | Preferred for low-noise transimpedance or precision active filtering where distortion floor matters more than raw speed. | Choose when system SNR dominates over slew rate - e.g., optical receiver front ends or medical ultrasound beamforming. |
Compared with LMH6715MA, LMH6720MA trades verified video performance for higher bandwidth and higher power, while THS3202D sacrifices some slew rate to achieve significantly lower noise and distortion - making it better suited for precision analog signal chains where fidelity outweighs speed.

FAQ
What is the maximum load capacitance LMH6715MA can drive without instability?
The LMH6715MA can drive up to 100pF capacitive load stably with no series resistance. For larger loads, a series resistor (Rs) at the output is required - Figure 26 in the datasheet shows Rs = 15Ω optimizes settling for 500pF, and Rs = 47Ω for 2000pF. Exceeding these values without Rs risks peaking and oscillation due to feedback loop phase shift.
Does LMH6715MA support single-supply operation?
No, LMH6715MA is specified only for split-supply operation (±5V to ±6V). Its common-mode input range is ±2.2V and output swing is symmetric about ground; attempting single-supply biasing violates absolute maximum ratings and causes input stage saturation. Use rail-to-rail op amps like OPA837 for true single-supply video applications.
How does LMH6715MA differ from CLC412 in practical design?
LMH6715MA replaces CLC412 with improved differential gain/phase (0.02% vs. 0.05%), lower power (5.8mA vs. 7.5mA/channel), and tighter channel matching. To match CLC412 bandwidth, use RF ≈ 700Ω instead of 500Ω. Layout rules remain identical, but LMH6715MA's lower noise and higher slew rate enable wider dynamic range in modern HDTV systems.
Can LMH6715MA be used in transimpedance amplifier configurations?
Yes - Figure 36 in the datasheet shows a validated dual-channel transimpedance design using LMH6715MA. The non-inverting input's lower current noise (1.4pA/√Hz) serves as the photodiode input, while the second channel provides stable negative feedback. RF sets gain; RT adjusts frequency compensation to prevent oscillation with high-capacitance detectors.
What thermal derating applies to LMH6715MA in SOIC package?
With θJA = 145°C/W, LMH6715MA's maximum power dissipation drops from 690mW at 25°C ambient to 414mW at 70°C ambient. At 85°C max operating temperature, Pmax = (150 − 85)/145 = 0.45W. Derate linearly above 25°C; ensure copper area and airflow meet TI's SOIC thermal guidelines to avoid junction temperatures exceeding +150°C.
