Product details
Overview
The MAX4450EUK 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 a +4.5V to +11V single supply - making it ideal for 75Ω video line driving in surveillance systems and set-top boxes.
For engineers reviewing the MAX4450EUK datasheet, MAX4450EUK pinout, MAX4450EUK application, or MAX4450EUK equivalent, key selection criteria include its SC70-5 package footprint, 55mV rail-to-rail output swing margin, low 6.5mA quiescent current per amplifier, and verified NTSC-compliant distortion performance at 5MHz.
Technical Context
The MAX4450EUK employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its input stage supports common-mode voltages extending beyond VEE (ground) and up to 2.25V below VCC, enabling true ground-sensing operation in single-supply systems.
Output stage design incorporates local feedback to maintain low open-loop output impedance (~1.5Ω), ensuring stable gain across varying load conditions including 75Ω and 100Ω video terminations. Stability is preserved via internal unity-gain compensation and recommended 24Ω feedback resistor in noninverting configurations.

Pinout & Package
The MAX4450EUK is housed in a 5-pin SC70 package (package code X5-1), measuring 2.0mm × 1.25mm × 0.9mm with 0.65mm lead pitch. This ultra-small outline supports high-density PCB layouts in space-constrained video modules and portable test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | Accepts differential input signals; supports common-mode range down to VEE − 0.2V |
| 2 - IN+ | Noninverting input | Enables ground-referenced signal acquisition in single-supply video routing |
| 3 - VEE | Negative supply / ground | Reference node for single-supply operation; must be tied to system ground |
| 4 - VCC | Positive supply | Accepts +4.5V to +11V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
| 5 - OUT | Amplifier output | Rail-to-rail capable; drives 75Ω coaxial lines directly when terminated properly |

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 | Higher 1.7GHz GBW but 12mA IQ; SO-8 only; no rail-to-rail output | Requires dual supply for full swing; less suitable for 5V single-supply video line driving | Prefer MAX4450EUK when rail-to-rail output, low IQ, and SC70 size are mandatory |
| ADA4817-1AKSZ-R7 | 1GHz GBW, 1.3pF input capacitance, FET input; 3.7mA IQ; SC70-6 package | Superior noise (4nV/√Hz) but lacks video-optimized DG/DP specs; not NTSC-validated | Choose MAX4450EUK for broadcast-grade video; ADA4817-1 for low-noise precision instrumentation |
Compared with LMH6702MF/NOPB and ADA4817-1AKSZ-R7, the MAX4450EUK uniquely combines NTSC-verified differential gain/phase, rail-to-rail output in SC70-5, and 6.5mA power consumption - making it the optimal choice for space- and power-constrained video signal chains where broadcast compliance is required.

FAQ
What is the maximum capacitive load the MAX4450EUK can drive without oscillation?
The MAX4450EUK is not optimized for direct capacitive loading. Driving >10pF without isolation causes peaking and instability. A series isolation resistor (20Ω–30Ω) is required - e.g., 27Ω supports up to 120pF while maintaining monotonic step response. For 75Ω transmission lines, proper double termination eliminates reactive load effects entirely. Always verify stability with actual layout parasitics in the final MAX4450EUK design.
Does the MAX4450EUK support dual-supply operation?
Yes, the MAX4450EUK operates from ±2.25V to ±5.5V dual supplies in addition to +4.5V to +11V single supply. Input common-mode range extends from VEE − 0.2V to VCC − 2.25V in both modes. However, the MAX4450EUK SC70-5 package pinout assumes VEE as ground in single-supply use; for dual supply, connect Pin 3 (VEE) to negative rail. PSRR is specified separately for each configuration.
What is the typical output voltage swing of the MAX4450EUK with a 75Ω load?
With a 75Ω load and +5V supply, the MAX4450EUK delivers ≥4.7VPP output swing (i.e., within 150mV of each rail), verified per AC Electrical Characteristics table. This exceeds the 2VPP requirement for standard CVBS video signals and maintains <0.1dB gain flatness to 55MHz. The exact swing depends on load resistance and supply voltage - consult Figure MAX4450-13 for VOUT vs. RLOAD curves in the MAX4450EUK datasheet.
Is the MAX4450EUK pin-compatible with other op amps in the MAX445x family?
No - the MAX4450EUK (single, SC70-5) is not pin-compatible with the MAX4451 (dual, SOT23-8/SO-8). Pin 1 is IN− on MAX4450EUK but INB− on MAX4451. Substituting them requires PCB redesign. The MAX4450EUK shares pinout only with identical variants (e.g., MAX4450EXK-T in SC70-5), not cross-family or dual-channel derivatives. Always validate pin mapping using the MAX4450EUK top-view diagram before layout.
How does the MAX4450EUK achieve 0.02% differential gain accuracy?
The MAX4450EUK achieves 0.02% differential gain via precision trimming of input-stage transistor matching and proprietary biasing that minimizes gain variation across signal amplitude and temperature. This is validated under NTSC conditions (RL = 150Ω, f = 4.43MHz chroma burst) and confirmed in Typical Operating Characteristics plot MAX4450-10. The specification holds across −40°C to +85°C and is intrinsic to the MAX4450EUK die design - no external calibration is needed.
