Product details
Overview
LMH6559MAX/NOPB from Texas Instruments is a high-speed, unity-gain closed-loop buffer IC designed for video signal distribution and wideband analog signal routing on PCBs. It delivers 1750 MHz small-signal bandwidth, 4580 V/μs slew rate, 0.06% differential gain / 0.02° differential phase at 3.58 MHz, −52 dBc THD at 20 MHz, and 75 mA linear output current under ±5 V supply.
For engineers reviewing the LMH6559MAX/NOPB datasheet, LMH6559MAX/NOPB pinout, LMH6559MAX/NOPB application, or LMH6559MAX/NOPB equivalent, key selection criteria include small-signal bandwidth vs. supply voltage (745 MHz at 5 V, 315 MHz at 3 V), output drive capability into 100 Ω, differential video fidelity, and SOIC-8 package compatibility with high-frequency layout practices.
Technical Context
The LMH6559MAX/NOPB is internally configured for fixed loop gain of one, eliminating external feedback components. Its 200 kΩ input resistance and 1.2 Ω output resistance enable low-loading, high-fidelity signal buffering without gain error or impedance mismatch in transmission-line-driven systems.
It operates across ±5 V, +5 V, or +3 V single-supply configurations, with supply current scaling from 3.5 mA (3 V) to 14 mA (±5 V). Performance degrades predictably with reduced supply: SSBW drops from 1750 MHz (±5 V) to 745 MHz (5 V) to 315 MHz (3 V), and slew rate falls from 4580 V/μs to 2070 V/μs to 770 V/μs.
Key Specifications

|---|---|
| Small Signal Bandwidth | 1750 MHz at ±5 V - supports full HD/SDI video and RF IF distribution without attenuation up to UHF |

Equivalent & Alternatives
The following parts are listed as comparable options for similar closed-loop buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6552MA/NOPB | Higher 2.8 GHz SSBW but requires external feedback; not unity-gain stable; 14-pin SOIC | Used where adjustable gain >1× or higher bandwidth justifies added layout complexity | Select LMH6552MA/NOPB only when gain >1× or >1750 MHz BW is required; LMH6559MAX/NOPB is simpler for fixed 1× video routing |

FAQ
What is the maximum small-signal bandwidth of the LMH6559MAX/NOPB?
The LMH6559MAX/NOPB achieves 1750 MHz small-signal bandwidth under ±5 V supply conditions with 100 Ω load and 0.5 VPP output. Bandwidth scales with supply: 745 MHz at +5 V and 315 MHz at +3 V. This makes LMH6559MAX/NOPB suitable for UHF video distribution and IF signal routing where flat frequency response up to 1.75 GHz is required without external compensation.
Does the LMH6559MAX/NOPB require external feedback resistors?
No. The LMH6559MAX/NOPB is internally configured for closed-loop unity gain (ACL = 1) and is fully unity-gain stable. No external feedback components are needed - simplifying layout, reducing BOM count, and ensuring consistent 0.97–0.998 V/V gain accuracy across temperature and supply variations. This distinguishes LMH6559MAX/NOPB from general-purpose op-amps like THS3201 or LMH6552, which require external resistors for gain setting.
Can the LMH6559MAX/NOPB drive 75 Ω video cables directly?
Yes. With 1.2 Ω output resistance and ±74 mA linear output current, the LMH6559MAX/NOPB can drive 75 Ω coaxial cables directly without series termination. Its 0.06% differential gain and 0.02° differential phase at 3.58 MHz meet broadcast video standards, and its 1750 MHz bandwidth preserves edge fidelity over long traces - enabling clean distribution in SDI switchers and broadcast monitor interfaces using LMH6559MAX/NOPB as the final output buffer.
What is the supply current consumption of the LMH6559MAX/NOPB?
The LMH6559MAX/NOPB draws 10–14 mA quiescent current under ±5 V supply, 4.7–8.5 mA at +5 V, and 2.4–4.5 mA at +3 V - scaling linearly with supply voltage. This low IQ enables use in portable test equipment and multi-channel video systems where thermal density and power budget are constrained, while still delivering 4580 V/μs slew rate and 1750 MHz bandwidth in the highest-performance configuration.
Is the LMH6559MAX/NOPB available in packages other than SOIC-8?
Yes. The LMH6559 is also offered in a 5-pin SOT-23 package (LMH6559MK/NOPB), but the LMH6559MAX/NOPB variant is exclusively in 8-pin SOIC (R-PDSO-G8). The SOIC-8 version provides dual VCC pins (Pins 4 and 8) for improved power-supply rejection and lower noise, and accommodates standard 10 nF + 100 nF decoupling per TI layout recommendations - making LMH6559MAX/NOPB the preferred choice for high-reliability video and instrumentation applications.
