Product details
Overview
MAX4451ESA+T from Maxim Integrated is a dual, 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 single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. Its 8-pin SO package supports compact video line driver and ADC interface designs.
For engineers reviewing the MAX4451ESA+T datasheet, MAX4451ESA+T pinout, MAX4451ESA+T application, or MAX4451ESA+T equivalent, key selection criteria include its 210MHz small-signal bandwidth, rail-to-rail output swing within 55mV of rails, input common-mode range extending beyond ground, low 6.5mA per amplifier quiescent current, and verified performance in NTSC video routing and CCD imaging systems.
Technical Context
The MAX4451ESA+T employs voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth without sacrificing stability at unity gain. Its input stage supports common-mode voltages down to VEE − 200mV and up to VCC − 2.25V, enabling ground-sensing operation in single-supply configurations.
The output stage uses local feedback to maintain low open-loop output impedance (1.5Ω typical), ensuring stable gain under varying load conditions. It is internally compensated and requires only a 24Ω feedback resistor in unity-gain configuration to optimize AC response and suppress parasitic LC resonance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Higher 1.8GHz bandwidth but higher 11.5mA quiescent current; not rail-to-rail output (clips ~1.2V from rails) | Better suited for RF IF amplification than video line driving due to limited output swing and higher power | Select when >1GHz bandwidth is mandatory and rail-to-rail output is not required |
| ADA4817-2ARZ | Lower 1GHz bandwidth, 1.3mA quiescent current, rail-to-rail output, but 110V/µs slew rate (vs. 485V/µs) | Optimized for precision low-noise applications (4.3nV/√Hz) rather than video fidelity (DG/DP not specified) | Select for low-power, low-noise instrumentation where video-grade differential gain/phase is not needed |
Compared with LMH6702MA/NOPB and ADA4817-2ARZ, the MAX4451ESA+T uniquely combines 210MHz bandwidth, 485V/µs slew rate, rail-to-rail output, and broadcast-grade 0.02%/0.08° video linearity in a single 8-pin SO package-making it the optimal choice for cost-sensitive, space-constrained video routing and CCD driver applications.

FAQ
What is the operating temperature range for the MAX4451ESA+T?
The MAX4451ESA+T is rated for continuous operation from −40°C to +85°C. This industrial temperature range is validated across all electrical specifications in the datasheet, including bandwidth, slew rate, and differential gain/phase performance. The device maintains 210MHz −3dB bandwidth and 0.02%/0.08° video linearity throughout this full range, making MAX4451ESA+T suitable for outdoor surveillance equipment and automotive infotainment displays.
Does the MAX4451ESA+T require external compensation for unity-gain stability?
No, the MAX4451ESA+T is internally compensated and unity-gain stable. When configured for unity gain, it requires only a 24Ω resistor in series with the feedback path to optimize AC response and suppress parasitic resonance. This resistor value is explicitly specified in the MAX4451ESA+T datasheet and has been validated across process, voltage, and temperature corners. No additional capacitors or network compensation is needed for stable operation.
Can the MAX4451ESA+T drive 75Ω coaxial cables directly?
Yes, the MAX4451ESA+T can drive 75Ω coaxial cables directly when used in a properly terminated configuration. Its rail-to-rail output delivers >4.9VPP into 75Ω with <0.02% differential gain error, and its low 1.5Ω open-loop output impedance ensures minimal interaction with cable impedance. For optimal performance, use back-termination at the load end and place the MAX4451ESA+T close to the connector to minimize stub length and preserve signal integrity in video line driver applications.
What is the input common-mode voltage range of the MAX4451ESA+T?
The MAX4451ESA+T input common-mode voltage range extends from (VEE − 0.2V) to (VCC − 2.25V). In a single +5V supply configuration (VEE = 0V), this means the inputs operate from −200mV to +2.75V - allowing ground-referenced video signals and sensor outputs to be amplified without level-shifting. This ground-sensing capability is confirmed in the datasheet's DC electrical characteristics table and is critical for interfacing with legacy analog video sources and CCD sensor outputs.
How does the MAX4451ESA+T compare to the single-channel MAX4450 in terms of pin compatibility?
The MAX4451ESA+T is not pin-compatible with the MAX4450. The MAX4450 uses a 5-pin SC70 or SOT23 package with pins: OUT, VEE, IN+, IN−, VCC. The MAX4451ESA+T uses an 8-pin SO package with dedicated pins for two independent amplifiers (INA−, INA+, OUTA, VEE, VCC, INB−, INB+, OUTB). While both share identical electrical specifications per channel, their physical layouts, pin counts, and terminal assignments differ fundamentally - requiring separate PCB footprints and layout plans for each device.
