Product details
Overview
MAX4450EUK-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 delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and 0.02%/0.08° differential gain/phase error while operating from +4.5V to +11V single supply - ideal for battery-powered surveillance video line drivers and ADC interface circuits.
For engineers reviewing the MAX4450EUK-T datasheet, MAX4450EUK-T pinout, MAX4450EUK-T application, or MAX4450EUK-T equivalent, key selection criteria include its SC70-5 package footprint, 55mV rail-to-rail output swing with 2kΩ load, low 6.5mA quiescent current per amplifier, and verified NTSC video performance at 75Ω termination.
Technical Context
The MAX4450EUK-T employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its input common-mode range extends beyond VEE (to VEE − 200mV) and up to VCC − 2.25V, enabling ground-sensing operation in single-supply systems.
Internally compensated for unity-gain stability, it requires only a 24Ω feedback resistor in unity-gain configuration to suppress parasitic LC resonance. Output stage local feedback ensures low open-loop output impedance (1.5Ω typical), minimizing gain sensitivity to load variations across 75Ω and 150Ω video applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 210MHz - supports full HD video baseband signal amplification without attenuation |
| Slew Rate | 485V/µs - enables clean 2V step response in ≤16ns, critical for fast video pulse fidelity |
| Rail-to-Rail Output Swing | Within 55mV of VEE and VCC with 2kΩ load - maximizes dynamic range in +5V systems (4.9VP-P output) |
| Differential Gain/Phase Error | 0.02% / 0.08° at NTSC - meets broadcast-grade video linearity requirements |
| Supply Voltage Range | +4.5V to +11V single supply - compatible with Li-ion battery (3.7V nominal) with LDO headroom or 5V/9V industrial rails |
| Quiescent Current | 6.5mA per amplifier - enables dual-channel portable instrumentation with <13mA total analog front-end draw |
| Input Common-Mode Range | VEE − 0.2V to VCC − 2.25V - allows direct connection to ground-referenced sensors in single-supply setups |
Pinout & Package
The MAX4450EUK-T is housed in a 5-pin SC70 package (package code U5-2), measuring 2.0mm × 1.25mm × 0.9mm with 0.65mm lead pitch. This ultra-small outline enables high-density PCB layouts in space-constrained video modules and portable test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 - IN+ | Noninverting Input | Ground-sensing input usable down to VEE − 200mV; enables single-supply sensor interfacing |
| 3 - VEE | Negative Supply / Ground | Reference for single-supply operation; must be connected to system ground or negative rail |
| 4 - OUT | Amplifier Output | Low-impedance rail-to-rail driver capable of sourcing/sinking >46mA into 75Ω loads |
| 5 - VCC | Positive Supply | Accepts +4.5V to +11V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but 12mA IQ; SOIC-8 only; no SC70 option | Better for RF IF stages; less suitable for space-constrained battery devices | Choose when >500MHz small-signal bandwidth is required and board area is not constrained |
| ADA4891-1ARJZ-R7 | Lower 225MHz bandwidth, 4.4mA IQ, same SC70-5 package | Optimized for lower power; slightly higher 0.05% DG error limits NTSC use | Prefer for cost-sensitive, non-broadcast video or general-purpose high-speed buffering where 0.02% DG is not mandatory |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, the MAX4450EUK-T uniquely balances 210MHz bandwidth, 6.5mA quiescent current, SC70-5 footprint, and broadcast-grade 0.02%/0.08° video linearity - making it the optimal choice for compact, battery-aware video signal conditioning where NTSC/PAL fidelity is critical.

FAQ
What is the maximum capacitive load the MAX4450EUK-T can drive without oscillation?
The MAX4450EUK-T is not optimized for direct capacitive loading. Driving >10pF without isolation causes peaking and instability. As shown in Figure 4 of the datasheet, a 27Ω series isolation resistor (RS) enables stable operation up to 120pF. For 75Ω video lines, back-termination eliminates reactive load effects. Always use RS = 20–30Ω when driving cables or PCB traces with significant capacitance - this applies directly to the MAX4450EUK-T design.
Does the MAX4450EUK-T support true single-supply operation with input referenced to ground?
Yes. The MAX4450EUK-T features a ground-sensing input stage: its common-mode input range extends to VEE − 200mV, allowing the IN+ pin to accept signals at 0V (ground) when VEE = 0V. This enables direct interfacing with ground-referenced sensors or DAC outputs in +5V systems - a confirmed specification for the MAX4450EUK-T under DC electrical characteristics.
What is the recommended feedback resistor value for unity-gain configuration of the MAX4450EUK-T?
The MAX4450EUK-T requires a 24Ω resistor (RF) in the feedback path for unity-gain stability, as specified in the Applications Information section. This value mitigates parasitic LC resonance caused by layout inductance and feedback capacitance. Using RF ≠ 24Ω risks degraded AC response or oscillation - this requirement is explicitly validated for the MAX4450EUK-T in the datasheet's "Unity-Gain Configuration" subsection.
Can the MAX4450EUK-T replace the MAX4450EXK-T in existing designs?
Yes - both MAX4450EUK-T and MAX4450EXK-T share identical electrical specifications, temperature range (−40°C to +85°C), and SC70-5 package. The only difference is marking: EXK-T uses "AAA" top mark, EUK-T uses "ADKP". Pinout, thermal performance, and AC/DC parameters are fully interchangeable; no layout or schematic changes are needed when substituting MAX4450EUK-T for MAX4450EXK-T.
Is the MAX4450EUK-T suitable for driving 75Ω coaxial cable in CCTV applications?
Yes. The MAX4450EUK-T is explicitly characterized for 75Ω video line driving: typical operating circuit shows 75Ω source termination, and AC specs include differential gain/phase error measured at RL = 150Ω (dual-terminated) and distortion tested into 75Ω. Its 485V/µs slew rate and 0.02%/0.08° NTSC performance make it qualified for professional CCTV and broadcast video routing - confirmed in the Applications and Typical Operating Characteristics sections for the MAX4450EUK-T.
