Product details
Overview
LT6206CMS8#PBF from Analog Devices (formerly Linear Technology) is a dual, low-cost, voltage-feedback operational amplifier optimized for 100MHz video signal processing in single-supply systems. It delivers 450V/μs slew rate, rail-to-rail output swing within 60mV of rails, and 50mA output drive per channel at 3V–5V supply. Its input common-mode range includes ground-enabling direct interface with DC-coupled video sources such as RGB, YPbPr, or coaxial cable drivers in automotive displays and baseband video splitters.
For engineers reviewing the LT6206CMS8#PBF datasheet, LT6206CMS8#PBF pinout, LT6206CMS8#PBF application, or LT6206CMS8#PBF equivalent, key selection criteria include guaranteed 100MHz gain-bandwidth at 3V, channel separation >90dB at 10MHz, input offset voltage ≤3.5mV (typ), rail-to-rail output swing under load, and MS8 package compatibility with standard dual op-amp footprints.
Technical Context
The LT6206CMS8#PBF employs a high-slew-rate complementary-input stage with back-to-back input diodes limiting differential voltage to ±1.4V, enabling robust operation with overvoltage transients. Its output stage uses a complementary drive generator to achieve rail-to-rail swing while sourcing/sinking ≥25mA at 3V–5V.
It maintains stable unity-gain performance driving 20pF capacitive loads; larger loads require series output resistors (10Ω–50Ω) to suppress ringing. Channel isolation exceeds 90dB at 10MHz, supporting dual-channel applications like RGB amplification without crosstalk-induced color distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 100MHz at 3V/5V - enables stable closed-loop gain ≥2 up to 50MHz video bandwidth |
| Slew Rate | 450V/μs - supports full-scale 2V step response in <25ns, critical for NTSC/PAL sync edge fidelity |
| Output Drive Current | ±50mA per amplifier - drives 75Ω back-terminated coaxial cables (150Ω effective load) at 2VP-P |
| Input Common-Mode Range | 0V to V+ – 2V - accepts ground-referenced video signals without level-shifting circuitry |
| Rail-to-Rail Output Swing | Within 60mV of V+ and V– at 5mA load - preserves dynamic range in 3.3V systems with 1VP-P video signals |
| Channel Separation | 90dB at 10MHz - prevents luminance-chrominance crosstalk in dual-channel RGB or Y/C paths |
| Supply Voltage Range | 2.7V to 12.6V - operates from single 3.3V or 5V rails, or split ±5V supplies |
Pinout & Package
LT6206CMS8#PBF is housed in an 8-lead plastic MSOP (MS8) package, 3mm × 3mm × 1.1mm, with standard dual op-amp pinout compatible with industry footprint requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers amplified signal; requires local 0.01μF bypass capacitor within 6mm of pin |
| 2 (–IN A) | Inverting input A | Accepts feedback network; sensitive to stray capacitance-keep trace short and guard |
| 3 (+IN A) | Non-inverting input A | DC-coupled video input node; protected by back-to-back diodes limiting differential voltage to ±1.4V |
| 4 (V–) | Negative supply rail | Ground reference for single-supply operation; must be low-impedance plane |
| 5 (V+) | Positive supply rail | 3.3V or 5V supply; bypass with 0.01μF ceramic + 4.7μF electrolytic for heavy video loads |
| 6 (+IN B) | Non-inverting input B | Independent second channel input; shares no internal nodes with Channel A |
| 7 (–IN B) | Inverting input B | Second channel feedback node; layout symmetry recommended for matched performance |
| 8 (OUT B) | Amplifier B output | Second independent output; capable of simultaneous 2VP-P drive into 150Ω |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4817-2ARMZ | Higher GBW (1GHz), lower noise (4nV/√Hz), but higher supply current (18mA/ch) and no guaranteed 3V operation | Better for precision ADC buffering or RF IF stages; less suitable for battery-powered 3.3V video systems | Choose ADA4817-2ARMZ only if >500MHz bandwidth and sub-5nV/√Hz noise are required-and power budget allows |
| LMH6629MA/NOPB | Similar 100MHz GBW and 450V/μs slew, but wider supply range (2.7V–12.6V), higher input bias current (1.2μA vs 10μA typ), and SOIC-8 package | Direct PCB replacement possible with layout adaptation; slightly higher offset drift (15μV/°C vs 7μV/°C) | LMH6629MA/NOPB offers same electrical performance in SOIC-8; select when MSOP footprint is unavailable or thermal relief is needed |
Compared with ADA4817-2ARMZ and LMH6629MA/NOPB, LT6206CMS8#PBF provides optimal balance of 100MHz bandwidth, 3.3V operation, rail-to-rail swing, and MSOP footprint for cost-sensitive video routing-without over-specifying noise or power where unnecessary.

FAQ
What is the minimum supply voltage required for stable operation of the LT6206CMS8#PBF?
The LT6206CMS8#PBF operates reliably down to 2.7V total supply voltage (V+ to V–), with full AC/DC specifications guaranteed at 3V and 5V. At 2.7V, gain-bandwidth remains ≥65MHz and slew rate ≥350V/μs-sufficient for SD video applications. Below 2.7V, performance degrades nonlinearly and is not characterized.
Can the LT6206CMS8#PBF drive a 75Ω coaxial cable directly without external termination?
No-the LT6206CMS8#PBF must be used with proper source termination. For 75Ω coax, configure it as a back-terminated driver: place a 75Ω resistor in series with each output, and ensure the load end is also terminated in 75Ω. This forms a 2:1 divider, requiring the LT6206CMS8#PBF to deliver 2VP-P to achieve 1VP-P at the receiver-well within its 50mA drive capability.
Does the LT6206CMS8#PBF support AC-coupled video inputs, and what design considerations apply?
Yes, the LT6206CMS8#PBF supports AC-coupled video, but requires careful DC biasing. Because black-level wander can reach ±0.56V in NTSC, the input common-mode voltage must be set mid-supply (e.g., 1.65V on 3.3V rail) using precision resistive dividers. A clamping circuit (e.g., sync-tip clamp with Schottky diode) reduces this wander to ±0.07V, improving headroom and reducing supply margin requirements.
What is the typical input offset voltage of the LT6206CMS8#PBF, and how does it affect video DC accuracy?
The LT6206CMS8#PBF has a typical input offset voltage of 1mV (max 3.5mV at 25°C, 6mV over 0°C–70°C). In a DC-coupled 1VP-P video system, this introduces ≤0.1% gain-independent DC error-equivalent to ~1mV shift in black level. For broadcast-grade accuracy, use the LT6206IMS8#PBF (industrial grade) or add external nulling circuitry.
Is the LT6206CMS8#PBF pin-compatible with other dual op-amps in MSOP-8 packages?
The LT6206CMS8#PBF uses standard dual op-amp pinout (OUT A, –IN A, +IN A, V–, V+, +IN B, –IN B, OUT B), matching industry conventions. It is functionally and pinout-compatible with LMH6629MA/NOPB and ADA4851-2ARMZ in MSOP-8-but not electrically identical. Always verify supply current, noise, and bandwidth requirements before substitution.
