Product details
Overview
MAX4350EXK+T 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 ideal for NTSC video line driving and ADC interface applications.
For engineers reviewing the MAX4350EXK+T datasheet, MAX4350EXK+T pinout, MAX4350EXK+T application, or MAX4350EXK+T equivalent, key selection criteria include its SC70-5 package footprint, rail-to-rail output swing within 125mV of rails, input common-mode range extending to VEE, low 6.9mA quiescent current per amplifier, and verified performance in 75Ω/150Ω video termination configurations.
Technical Context
The MAX4350EXK+T employs a voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining unity-gain stability. Its input stage supports common-mode voltages from VEE to (VCC − 2.25V), and its output stage uses local feedback to maintain low open-loop output impedance (~8Ω) and minimize load-dependent gain variation.
Designed specifically for AC-coupled, high-fidelity analog signal paths, the device features optimized internal compensation and requires only a 24Ω feedback resistor in unity-gain configuration to suppress parasitic LC resonance. It is not intended for highly capacitive loads without series isolation resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Wider 1.8GHz bandwidth but higher 12.5mA supply current; requires external compensation for unity gain | Better suited for RF IF amplification; less optimal for video due to higher power and instability at AVCL = 1 | Select MAX4350EXK+T for cost-sensitive, low-power, unity-gain video line drivers where 210MHz suffices |
| ADA4817-1ARMZ | Lower 1.05nV/√Hz input voltage noise (vs. 10nV/√Hz), but 100MHz bandwidth and no guaranteed rail-to-rail output swing | Preferred in precision low-noise preamp stages; not validated for NTSC differential gain/phase compliance | Choose MAX4350EXK+T when video fidelity, small SC70 footprint, and guaranteed rail-to-rail output are mandatory |
Compared with LMH6702MF/NOPB and ADA4817-1ARMZ, the MAX4350EXK+T uniquely balances video-grade AC performance, ultra-low power, unity-gain stability, and SC70 packaging - making it the only option among the three qualified for NTSC-compliant 75Ω line driving in space-constrained consumer enclosures.

FAQ
What is the operating supply voltage range for the MAX4350EXK+T?
The MAX4350EXK+T operates from dual supplies ranging from ±4.5V to ±5.5V. It is specified for full performance across this range with typical operation at ±5V. The device is not rated for single-supply operation above 10V total, and VCC-to-VEE must not exceed +12V. Absolute maximum ratings prohibit exceeding these limits to avoid permanent damage.
Does the MAX4350EXK+T support rail-to-rail input common-mode voltage?
The MAX4350EXK+T supports rail-to-rail *output* swing but has an input common-mode voltage range from VEE to (VCC − 2.25V). This means the input can go down to the negative rail (VEE) but only up to 2.25V below the positive rail - not fully rail-to-rail on the high side. This design enables robust ground-sensing capability while maintaining high CMRR across the usable range.
Can the MAX4350EXK+T drive a 75Ω coaxial cable directly?
Yes - the MAX4350EXK+T is characterized for 75Ω and 150Ω loads and is commonly used in unity-gain line driver configurations with 24Ω feedback resistors and proper back-termination. Its low 1.5Ω output impedance at 10MHz and 485V/µs slew rate ensure minimal signal degradation. However, capacitive loads >5pF require a series isolation resistor (e.g., 20–30Ω) to prevent peaking or oscillation.
What is the thermal performance of the MAX4350EXK+T in SC70-5 package?
In the SC70-5 package, the MAX4350EXK+T has a maximum continuous power dissipation of 200mW at +70°C, derating linearly by 2.5mW/°C above that temperature. At full 6.9mA quiescent current per amplifier on ±5V supplies, power dissipation is ~69mW - well within safe operating limits even at +85°C ambient, assuming adequate PCB copper pour for heat spreading.
Is the MAX4350EXK+T pin-compatible with other SC70-5 op amps like the MAX4477 or OPA355?
No - the MAX4350EXK+T has a unique pinout (IN−, IN+, VEE, OUT, VCC) that differs from industry-standard SC70-5 op amps such as the OPA355 (V−, V+, OUT, GND, V+) or MAX4477 (V−, V+, OUT, V+, GND). Substitution requires PCB layout revision. Always verify pin mapping against the MAX4350EXK+T top-view diagram before replacement.
