Product details
Overview
LMH6559MA/NOPB from Texas Instruments is a high-speed, unity-gain closed-loop buffer IC designed for video signal distribution and high-frequency analog signal routing on PCBs. It delivers 1750 MHz small-signal bandwidth, 4580 V/µs slew rate, and 0.06% / 0.02° differential gain/phase at 3.58 MHz under ±5V operation - enabling precise composite video buffering in broadcast and instrumentation systems.
For engineers reviewing the LMH6559MA/NOPB datasheet, LMH6559MA/NOPB pinout, LMH6559MA/NOPB application, or LMH6559MA/NOPB equivalent, key selection criteria include its 1.2 Ω output resistance, 75 mA linear output current capability, −52 dBc THD at 20 MHz, single-supply compatibility down to 3 V, and SOIC-8 package suitability for high-density layout with minimal board-level compensation.
Technical Context
The LMH6559MA/NOPB is internally configured for fixed unity voltage gain (ACL = 0.97–0.998 V/V), eliminating external feedback components and ensuring stable operation into resistive, capacitive, and transmission-line loads. Its VIP10 bipolar process enables ultra-fast transient response (0.4 ns rise time) and low distortion across wide supply ranges (±5V, +5V, or +3V).
It features 200 kΩ input resistance, 1.2–2.3 Ω frequency-dependent output resistance, and rail-to-rail output swing capability - supporting DC-coupled video clamping, active filter buffering, and peak detector drive without level-shifting circuitry. Input offset voltage remains below 20 mV over −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small Signal Bandwidth | 1750 MHz at ±5V - supports full HD/SDI baseband video distribution without gain peaking or phase roll-off |
| Slew Rate | 4580 V/µs - enables faithful reproduction of fast-edged signals (e.g., sync pulses, digital video transitions) |
| Differential Gain/Phase | 0.06% / 0.02° at 3.58 MHz - meets NTSC/PAL broadcast-grade color fidelity requirements |
| Total Harmonic Distortion | −52 dBc at 20 MHz into 100 Ω - ensures minimal spectral contamination in wideband test equipment |
| Output Resistance | 1.2 Ω at 100 kHz - allows direct 50 Ω/75 Ω transmission line driving with minimal impedance mismatch loss |
| Supply Current | 10 mA typical at ±5V - achieves high-speed performance with low power overhead in multi-channel systems |
| Input Resistance | 200 kΩ - minimizes loading on preceding stages (e.g., DAC outputs, filter nodes) |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DR | Higher 2.5 GHz SSBW but 12 mA supply current; no guaranteed differential gain spec | Better suited for RF sampling clock distribution than broadcast video due to lack of DG/DP characterization | Select when >2 GHz bandwidth is required and video fidelity metrics are secondary |
| LMH6702MA | 1.8 GHz SSBW, 1000 V/µs slew rate, 10 mA supply current; specified for 0.1% DG at 3.58 MHz | Lower slew rate limits pulse fidelity in fast-edge test point applications | Choose for cost-sensitive video routing where 0.1% DG is acceptable and 4580 V/µs is unnecessary |
Compared with THS3201DR and LMH6702MA, the LMH6559MA/NOPB uniquely balances broadcast-grade video linearity (0.06% DG), ultra-high slew rate (4580 V/µs), and low quiescent current (10 mA), making it optimal for multi-channel SDI distribution and precision test point buffering where both speed and fidelity are critical.

FAQ
What is the maximum supply voltage rating for LMH6559MA/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMH6559MA/NOPB is 13 V. Operation beyond this limit risks permanent damage. Recommended operating range is ±5 V (10 V total), +5 V single-supply, or +3 V single-supply - all validated per TI SNOSA57C. The LMH6559MA/NOPB must never be operated above 13 V across its supply pins.
Does LMH6559MA/NOPB require external feedback components to operate?
No. The LMH6559MA/NOPB is internally configured for closed-loop unity gain (ACL ≈ 1 V/V) and requires no external resistors or capacitors for basic operation. Its pinout integrates matched input terminals to enforce fixed gain, simplifying layout and eliminating gain-setting errors. External components are only needed for specialized biasing or compensation in non-standard configurations.
Can LMH6559MA/NOPB drive 75 Ω coaxial cables directly?
Yes. With 1.2 Ω output resistance at low frequencies and 75 mA linear output current, the LMH6559MA/NOPB can drive 75 Ω loads directly - including multiple parallel coaxial cables - while maintaining <0.1 dB gain flatness up to 200 MHz. For optimal return loss, series termination or proper PCB impedance control is recommended per TI application notes.
What is the guaranteed differential gain performance of LMH6559MA/NOPB?
The LMH6559MA/NOPB guarantees 0.06% differential gain error at 3.58 MHz under ±5V supply and RL = 150 Ω to 0 V conditions, as specified in the TI SNOSA57C datasheet. This value is tested and ensured across production lots, making it suitable for NTSC/PAL broadcast equipment where color fidelity is strictly regulated.
Is LMH6559MA/NOPB compatible with single-supply 3 V operation?
Yes. LMH6559MA/NOPB supports single-supply operation from 3 V (V+ = 3 V, V− = 0 V), delivering 315 MHz small-signal bandwidth, 770 V/µs slew rate, and 0.29% differential gain at 3.58 MHz. Input common-mode range includes ground, and output swing reaches 2.07 V positive and 0.97 V negative into 2 kΩ, enabling use in battery-powered instrumentation.
