Product details
Overview
MAX4350EXK+ from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output operational amplifier optimized for high-speed video and instrumentation signal conditioning. It operates from dual ±5V supplies, delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and achieves 0.02% differential gain / 0.08° differential phase error into 150Ω - making it suitable for NTSC video line driving and ADC interface buffering.
For engineers reviewing the MAX4350EXK+ datasheet, MAX4350EXK+ pinout, MAX4350EXK+ application, or MAX4350EXK+ equivalent, this page provides verified technical context, real-world design meaning of key specs, SC70-5 package layout, and validated alternative options for video signal-path and high-fidelity analog front-end designs.
Technical Context
The MAX4350EXK+ employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its input stage supports common-mode voltages down to VEE (–5V) and up to VCC – 2.25V (+2.75V), enabling ground-sensing operation in dual-supply systems.
It features internally compensated unity-gain stability, rail-to-rail output swing within 125mV of each supply rail under 2kΩ load, and low open-loop output impedance (8Ω) for reduced gain sensitivity to load variations - critical for driving 75Ω or 150Ω video lines and ADC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 210MHz -3dB small-signal bandwidth enables full HD video signal amplification without attenuation. |
| Slew Rate | 485V/µs supports clean 2V-step transitions in ≤16ns, essential for fast-settling video and pulse applications. |
| Differential Gain/Phase | 0.02%/0.08° at NTSC frequency ensures broadcast-grade color fidelity in surveillance and set-top box video paths. |
| Supply Current | 6.9mA per amplifier enables low-power, high-bandwidth operation in space-constrained portable or multi-channel systems. |
| Output Swing | Rail-to-rail swing within 125mV of ±5V rails delivers >9.75Vpp dynamic range into 2kΩ, preserving signal headroom. |
| Harmonic Distortion | –63dB THD at 5MHz minimizes spurious content in CCD imaging and analog-to-digital converter interface circuits. |
| Input Voltage Range | Common-mode range extends to VEE (–5V), allowing direct connection to ground-referenced sensors or DAC outputs. |
Pinout & Package
The MAX4350EXK+ is housed in a 5-pin SC70 package (3.0mm × 1.75mm × 0.9mm), optimized for ultra-compact PCB layouts in video routing, camera modules, and portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN– | Inverting input | Accepts feedback network for stable gain configurations; requires low-parasitic layout for >100MHz performance. |
| 2 - IN+ | Noninverting input | High-impedance node (3MΩ common-mode); supports DC-coupled sensor or DAC interface with VEE-referenced common mode. |
| 3 - VEE | Negative power supply | Must be bypassed with 0.1µF capacitor to ground; serves as reference for input common-mode range extension. |
| 4 - OUT | Amplifier output | Drives 75Ω/150Ω loads directly; rail-to-rail swing enables full utilization of ±5V supply in video line drivers. |
| 5 - VCC | Positive power supply | Bypassed locally to minimize PSRR degradation; supports operation across ±4.5V to ±5.5V supply range. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Wider 1.8GHz bandwidth but higher 12.5mA supply current; not rail-to-rail output (clips ~1.2V from rails). | Better suited for RF IF amplification than video line driving due to output swing limitation and higher power. | Select when >1GHz small-signal bandwidth is required and rail-to-rail output is not mandatory. |
| ADA4817-1ARMZ | Lower 1.05GHz bandwidth, 1.1nV/√Hz input noise, rail-to-rail output, but only specified for +5V single supply (not ±5V dual). | Optimized for low-noise, single-supply portable instrumentation - lacks dual-supply flexibility and NTSC-validated video specs. | Prefer for battery-powered, low-noise sensor interfaces where dual-supply operation and video-grade DG/DP are unnecessary. |
Compared with LMH6702MF/NOPB and ADA4817-1ARMZ, the MAX4350EXK+ uniquely combines ±5V dual-supply operation, rail-to-rail output, NTSC-validated 0.02%/0.08° video performance, and ultra-small SC70-5 packaging - making it the only option qualified for space-constrained, broadcast-compliant video line drivers.

FAQ
What supply voltage range does the MAX4350EXK+ support?
The MAX4350EXK+ operates from dual ±4.5V to ±5.5V supplies, with typical characterization at ±5V. Its input common-mode range extends to VEE and up to VCC – 2.25V, and output swings to within 125mV of either rail under 2kΩ load - enabling robust performance across its full specified supply range. This makes the MAX4350EXK+ suitable for systems with minor rail tolerances or temperature-induced drift.
Is the MAX4350EXK+ unity-gain stable, and what external components are needed?
Yes, the MAX4350EXK+ is internally compensated for unity-gain stability. For optimal AC performance in unity-gain configuration, a 24Ω resistor (RF) is recommended in series with the feedback path to dampen parasitic LC resonance. No additional compensation capacitors or resistors are required - simplifying layout and reducing bill-of-materials cost in video line driver designs using the MAX4350EXK+.
Does the MAX4350EXK+ support rail-to-rail input operation?
No - the MAX4350EXK+ supports rail-to-rail *output* swing but has a limited input common-mode range: from VEE to VCC – 2.25V. While it senses down to the negative rail (VEE), it cannot accept inputs within 2.25V of VCC. This ground-sensing input architecture is intentional for video applications where the signal stays near mid-supply or negative rail, and is clearly specified in the MAX4350EXK+ datasheet DC characteristics table.
What is the typical differential gain and phase error of the MAX4350EXK+?
The MAX4350EXK+ delivers 0.02% differential gain error and 0.08° differential phase error under NTSC conditions with 150Ω load - measured and guaranteed across –40°C to +85°C. These values are explicitly documented in the "AC Electrical Characteristics" table and confirmed in Typical Operating Characteristics plots (MAX4350-11), making the MAX4350EXK+ suitable for broadcast-quality video signal paths where color fidelity is critical.
Can the MAX4350EXK+ drive 75Ω coaxial cables directly?
Yes - the MAX4350EXK+ is characterized to drive 75Ω loads with minimal peaking or ringing when used with proper termination. The typical operating circuit shows a 24Ω series resistor (RF) and 75Ω load (RTO), and the device maintains 0.1dB gain flatness to 55MHz into 75Ω. For longer cables or reactive loads, a small isolation resistor (20–30Ω) is recommended per the MAX4350EXK+ layout guidelines to preserve stability - confirming its suitability as a video line driver.
