Product details
Overview
MAX4350EUK+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 circuits.
For engineers reviewing the MAX4350EUK+T datasheet, MAX4350EUK+T pinout, MAX4350EUK+T application, or MAX4350EUK+T equivalent, key selection criteria include its SC70-5 package footprint, ±4.5V to ±5.5V supply range, rail-to-rail output swing within 125mV of rails, low 6.9mA quiescent current per amplifier, and verified performance in 75Ω/150Ω video termination topologies.
Technical Context
The MAX4350EUK+T employs a voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast settling (16ns to 0.1%). Its input stage supports common-mode voltages from VEE to (VCC − 2.25V), enabling ground-sensing operation in dual-supply systems.
Internally compensated for unity-gain stability, it uses a 24Ω feedback resistor (RF) in standard configurations to optimize AC response and suppress peaking caused by parasitic LC resonance. Output impedance remains low (1.5Ω at 10MHz) due to local feedback around the output stage, ensuring stable gain across varying loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 210MHz small-signal - supports full HD video baseband (up to ~150MHz) with margin. |
| Slew Rate | 485V/µs - enables clean 2V step response in ≤16ns, critical for fast pulse fidelity. |
| Output Swing | Rails ±125mV @ 2kΩ - delivers >9.75Vpp dynamic range from ±5V supplies. |
| Differential Gain/Phase | 0.02%/0.08° @ NTSC, RL = 150Ω - meets broadcast-grade video linearity requirements. |
| Quiescent Current | 6.9mA per amplifier - balances speed and power efficiency in portable or thermally constrained designs. |
| Input Common-Mode Range | VEE to (VCC − 2.25V) - allows input signals down to negative rail, supporting DC-coupled sensor interfaces. |
| THD + Noise | −63dB at 5MHz - ensures low distortion in high-fidelity analog signal chains. |
Pinout & Package
The MAX4350EUK+T is housed in a 5-pin SC70 package (JEDEC MO-203AA), measuring 2.0mm × 1.25mm × 0.8mm, with 0.65mm pitch and gull-wing leads. This ultra-small outline supports high-density PCB layouts in space-constrained video modules and portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting Input | Accepts differential input signal; supports common-mode down to VEE. |
| 2 - IN+ | Noninverting Input | Reference node for gain configuration; high-impedance (3MΩ common-mode). |
| 3 - VEE | Negative Power Supply | Connects to −5V (or ground in single-supply mode); defines lower rail reference. |
| 4 - OUT | Amplifier Output | Rail-to-rail capable output; drives 75Ω/150Ω video loads directly with minimal external components. |
| 5 - VCC | Positive Power Supply | Connects to +5V; supplies internal biasing and output stage; supports ±4.5V to ±5.5V operation. |
Key Features

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 (>100MHz) than video linearity-critical roles. | Choose when bandwidth >1GHz is required and power budget allows; not drop-in for MAX4350EUK+T video layouts. |
| ADA4817-1ACPZ-R7 | Lower 1.05GHz bandwidth, 1.1nV/√Hz input noise, and 10.5mA IQ; rail-to-rail input/output. | Stronger for precision low-noise preamp stages, weaker in differential gain/phase specs (0.05%/0.2°). | Select for sensor front-ends needing ultra-low noise; avoid where NTSC/PAL video fidelity is mandatory. |
Compared with LMH6702MF/NOPB and ADA4817-1ACPZ-R7, the MAX4350EUK+T uniquely balances broadcast-grade video linearity (0.02%/0.08°), ultra-small SC70-5 footprint, and unity-gain stability - making it the preferred choice for space-constrained, cost-sensitive video routing and ADC interface designs requiring guaranteed NTSC compliance.

FAQ
What supply voltage range does the MAX4350EUK+T support?
The MAX4350EUK+T operates from dual ±4.5V to ±5.5V supplies, with absolute maximum rating of ±6V. It is specified for stable operation across −40°C to +85°C ambient temperature. The device draws only 6.9mA quiescent current per amplifier at ±5V, making it suitable for power-sensitive video signal chains where thermal dissipation must be minimized while maintaining 210MHz bandwidth.
Does the MAX4350EUK+T require external compensation for unity-gain operation?
No, the MAX4350EUK+T is internally compensated for unity-gain stability. When used in unity-gain configurations, a 24Ω resistor (RF) is recommended in series with the feedback path to optimize AC performance and suppress peaking caused by parasitic capacitance. This value is validated in the MAX4350EUK+T datasheet and ensures flat gain response up to 55MHz (0.1dB) without oscillation or overshoot.
What is the output voltage swing capability of the MAX4350EUK+T?
The MAX4350EUK+T delivers rail-to-rail output swing, reaching within 125mV of both VCC and VEE under 2kΩ load conditions. At 150Ω (standard video load), it sustains >±4.25V swing, enabling >8.5Vpp signal amplitude from ±5V supplies. This performance is confirmed across temperature and ensures compatibility with 75Ω/150Ω video termination schemes used in surveillance and broadcast equipment.
Can the MAX4350EUK+T drive capacitive loads directly?
The MAX4350EUK+T is not optimized for direct capacitive loading and may exhibit peaking or oscillation above ~5pF without isolation. For loads >10pF (e.g., coaxial cables, PCB traces), a 20Ω–30Ω series isolation resistor is required between the output and capacitance. Datasheet Figure 2 and Figure 5 confirm stable closed-loop response with 27Ω RISO driving up to 120pF - a design practice essential for reliable MAX4350EUK+T deployment in video routing systems.
How does the MAX4350EUK+T perform in NTSC video applications?
The MAX4350EUK+T is characterized for NTSC video performance, delivering 0.02% differential gain error and 0.08° differential phase error into 150Ω loads - meeting or exceeding EIA-770.1 broadcast specifications. These values are measured across temperature and supply variations, confirming consistent color fidelity in set-top boxes, video switchers, and digital camera output stages where hue and saturation accuracy are critical.
