Product details
Overview
LMH6715 MDC from Texas Instruments (formerly National Semiconductor) is a dual wideband current-feedback operational amplifier designed for high-fidelity video signal processing and broadband analog systems. It delivers 400 MHz small-signal bandwidth at +2V/V gain, 1300 V/µs slew rate, and 0.02% / 0.02° differential gain/phase error driving four 75Ω back-terminated video loads - making it ideal for broadcast-quality NTSC/PAL video distribution and HDTV line drivers.
For engineers reviewing the LMH6715 MDC datasheet, LMH6715 MDC pinout, LMH6715 MDC application, or LMH6715 MDC equivalent, key selection criteria include its matched dual-channel AC performance, ±5V supply operation with 5.8 mA/channel quiescent current, flat 0.1 dB gain response to 100 MHz, and −70 dB channel-to-channel crosstalk at 10 MHz - all in an industry-standard 8-pin SOIC package.
Technical Context
The LMH6715 MDC employs National's VIP10™ complementary bipolar process and current-feedback topology, enabling gain-independent bandwidth optimization via external feedback resistor (RF) tuning - typically 500Ω for +2V/V gain. Its input stage features unmatched bias currents (±5–35 µA), requiring careful DC offset management in precision applications.
Each amplifier provides 70 mA output drive capability, ±3.9 V output swing into 100Ω at ±5V supplies, and operates over −40°C to +85°C. Channel matching is achieved through monolithic integration, yielding tight AC/DC tracking critical for differential line drivers, Sallen-Key filters, and IQ amplifiers in portable RF systems.

Pinout & Package
LMH6715 MDC is housed in an 8-pin SOIC package (NSC drawing M08A, θJA = 145°C/W), compatible with standard surface-mount assembly processes and thermal management practices for industrial video equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | High-current, low-impedance output capable of ±3.9 V swing into 100Ω load |
| 2 (−IN A) | Inverting input A | Current-input node for feedback configuration; requires precise RF placement to avoid instability |
| 3 (+IN A) | Non-inverting input A | Voltage-input node with 1 kΩ input resistance and 1 pF capacitance; sensitive to PCB parasitics |
| 4 (V−) | Negative supply rail | Accepts −5 V to −6 V; must be decoupled with low-ESR ceramic capacitor adjacent to pin |
| 5 (+IN B) | Non-inverting input B | Matched to Pin 3; enables independent dual-channel operation or differential configurations |
| 6 (−IN B) | Inverting input B | Matched to Pin 2; used with Pin 5 for second channel feedback loop |
| 7 (OUT B) | Amplifier B output | Electrically and thermally matched to Pin 1; supports synchronized dual-output timing |
| 8 (V+) | Positive supply rail | Accepts +5 V to +6 V; shared rail design requires low-inductance ground return path |
Key Features

Applications
| HDTV Video Distribution | IQ Signal Amplification |
|---|---|
Use Scenario: Driving multiple 75Ω coaxial outputs from a single HD video source in broadcast routing switchers. IC Role / Device Role / Timing Role: Dual-channel line driver with matched gain/phase to preserve chroma/luma timing alignment across outputs. Use Value: 0.02° differential phase error prevents visible color shift between parallel video paths; −70 dB crosstalk avoids ghosting during rapid scene transitions. | Use Scenario: Amplifying in-phase (I) and quadrature (Q) baseband signals in portable SDR transceivers.

IC Role / Device Role / Timing Role: Dual op amp configured as cascaded 2nd-order stages, leveraging matched AC response for consistent filter roll-off. Use Value: 0.1 dB gain flatness to 100 MHz ensures passband ripple <0.2 dB; 1300 V/µs slew rate prevents step-response distortion on fast transient inputs. | Use Scenario: Converting single-ended video or data signals to balanced differential outputs for noise-immune transmission over PCB traces or cables. IC Role / Device Role / Timing Role: One amplifier as inverting gain stage, the other as non-inverting - generating complementary outputs with sub-degree phase skew. Use Value: Matched propagation delay (<10 ps typical) and gain ensures common-mode rejection >60 dB at 50 MHz; 70 mA drive sustains signal integrity into 100Ω differential loads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual wideband video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6720 MDC | Single-channel version with identical specs; no dual-channel matching | Requires two units for dual functions; higher board area and power vs. LMH6715 MDC | Select when only one high-speed channel is needed or layout constraints prevent dual-amplifier integration |
| THS3202D | Higher 1.8 GHz bandwidth but 10 mA/channel supply current; no specified differential gain/phase data | Better suited for RF IF amplification than broadcast video; lacks NTSC/PAL validation | Prefer for >200 MHz signal chains where video fidelity is secondary to raw speed and settling time |
Compared with LMH6715 MDC, LMH6720 MDC offers identical per-channel performance but no inter-channel matching - limiting use in differential or multi-path video systems - while THS3202D trades verified video linearity for wider bandwidth and higher power, making it less suitable for NTSC/PAL compliance-critical designs.

FAQ
What is the recommended feedback resistor value for LMH6715 MDC in a +2V/V non-inverting configuration?
The recommended feedback resistor (RF) for LMH6715 MDC in +2V/V non-inverting configuration is 500Ω. This value ensures optimal stability, bandwidth, and gain flatness per the datasheet's Electrical Characteristics and Typical Performance plots. Using 300Ω yields marginal peaking and slightly higher bandwidth but risks instability with light loads (>300Ω), while values below 200Ω cause oscillation. Always verify RF selection with actual board parasitics and load conditions.
Does LMH6715 MDC support operation from a single supply?
No, LMH6715 MDC is specified for dual-supply operation only - ±5 V to ±6 V. Its common-mode input voltage range is ±2.2 V and output swing is asymmetric under single-supply biasing. Attempting single-supply use violates Absolute Maximum Ratings and causes input stage saturation, clipping, and undefined behavior. For single-supply video applications, consider TI's THS4631 or OPA695 as alternatives.
Can LMH6715 MDC drive four 75Ω back-terminated video loads simultaneously?
Yes, LMH6715 MDC is explicitly characterized to drive up to four 75Ω back-terminated video loads while maintaining 0.02% differential gain and 0.02° differential phase error for NTSC/PAL signals. Each channel delivers 70 mA output current and sustains ±3.5 V into 75Ω at ±5 V supplies. Layout best practices - including separate ground returns per channel and minimized feedback resistor parasitics - are essential to achieve this performance.
What is the maximum junction temperature and thermal resistance for LMH6715 MDC in SOIC package?
The maximum junction temperature for LMH6715 MDC is +150°C. In the 8-pin SOIC package (M08A), its thermal resistance from junction-to-ambient (θJA) is 145°C/W and junction-to-case (θJC) is 65°C/W. At 5.8 mA/channel and ±5 V supplies, quiescent power dissipation is ~58 mW per amplifier. Derating is required above +85°C ambient; maximum allowable ambient temperature at full load is ~110°C using θJA-based calculation.
Is LMH6715 MDC pin-compatible with CLC412?
No, LMH6715 MDC is not pin-compatible with CLC412. While LMH6715 MDC is documented as an "improved replacement" for CLC412 in functionality and performance, their pinouts differ: CLC412 uses an 8-pin SOIC but assigns V+ and V− to Pins 4 and 5, whereas LMH6715 MDC places V− at Pin 4 and V+ at Pin 8. Direct substitution requires PCB redesign. Matching bandwidth requires adjusting RF to ~700Ω for LMH6715 MDC versus CLC412's typical 500Ω.
