Product details
Overview
The MAX4450EXK+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 a +4.5V to +11V single supply. Its ultra-small SC70-5 package and 55mV rail-to-rail output swing make it ideal for space-constrained video line drivers and ADC interface circuits.
For engineers reviewing the MAX4450EXK+T datasheet, MAX4450EXK+T pinout, MAX4450EXK+T application, or MAX4450EXK+T equivalent, key selection criteria include its 210MHz small-signal bandwidth, 55MHz 0.1dB gain flatness, low 6.5mA quiescent current per amplifier, rail-to-rail output capability, and verified performance in NTSC video systems with <0.02% differential gain error.
Technical Context
The MAX4450EXK+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 extending beyond the negative rail (to VEE − 200mV) and up to VCC − 2.25V, enabling ground-sensing operation in single-supply configurations.
Internally compensated for unity-gain stability, the device requires only a 24Ω feedback resistor in unity-gain configuration to optimize AC response and suppress parasitic LC resonance. Output impedance remains low (<2Ω at DC) due to local feedback, ensuring minimal gain variation across load changes from 75Ω to 2kΩ.
Key Specifications

Pinout & Package
The MAX4450EXK+T 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-compact outline supports high-density PCB layouts in portable and space-constrained video modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 12.5mA IQ; SO-8 only; no rail-to-rail output | Better for RF IF amplification; unsuitable for rail-to-rail output video line driving | Choose LMH6702MF/NOPB only when >1GHz bandwidth is required and output swing beyond 1.2V from rails is acceptable |
| ADA4817-1ARMZ | 1GHz GBW, 2.5mA IQ, rail-to-rail output; 3.5nV/√Hz noise vs. 10nV/√Hz | Superior noise and speed for precision instrumentation; higher cost and larger 8-lead MSOP package | Choose ADA4817-1ARMZ when sub-4nV/√Hz noise and >500MHz bandwidth justify added cost and board area |

FAQ
What is the maximum capacitive load the MAX4450EXK+T can drive without oscillation?
The MAX4450EXK+T is not optimized for direct capacitive loading. Driving >10pF without isolation causes peaking and instability. A series isolation resistor (20–30Ω) must be placed between the MAX4450EXK+T output and any capacitive load-including PCB traces, connectors, or cables-to maintain phase margin. For 68pF loads, a 27Ω resistor restores flat frequency response, as validated in Figure 5 of the MAX4450EXK+T datasheet.
Does the MAX4450EXK+T support dual-supply operation?
Yes, the MAX4450EXK+T operates from dual supplies ranging from ±2.25V to ±5.5V. In dual-supply mode, VEE connects to the negative rail and VCC to the positive rail. The input common-mode range extends from (VEE − 200mV) to (VCC − 2.25V), and output swings within 55mV of both rails. PSRR is specified separately for single- and dual-supply conditions per Note 3 in the datasheet.
What is the recommended layout practice for the MAX4450EXK+T in high-frequency applications?
Maxim recommends microstrip or stripline PCB routing with characteristic impedance ≥50Ω, avoiding wire-wrap or IC sockets. Keep input/output traces short and straight, round corners instead of using 90° bends, and use surface-mount components exclusively. Bypass VCC to ground with a 0.1µF ceramic capacitor placed as close as possible to Pin 4. A two-layer board with solid ground plane is mandatory to preserve 210MHz bandwidth and minimize parasitic inductance.
Can the MAX4450EXK+T be used as a 75Ω video line driver without external resistors?
No-while the MAX4450EXK+T drives 75Ω loads with excellent differential gain/phase performance, it requires external 75Ω source termination for proper impedance matching. The typical operating circuit (Figure 1) shows a 500Ω series resistor at the output feeding a 75Ω coaxial line; this forms a proper source-terminated driver. Omitting termination causes reflections, ghosting, and degraded DG/DP performance in NTSC systems.
What is the guaranteed operating temperature range for the MAX4450EXK+T?
The MAX4450EXK+T is rated for continuous operation from −40°C to +85°C. All electrical specifications-including 210MHz bandwidth, 485V/µs slew rate, and 0.02%/0.08° differential gain/phase-are guaranteed across this full industrial temperature range. Absolute maximum ratings extend to −65°C storage and +150°C junction temperature, but functional operation outside −40°C to +85°C is not characterized or warranted.
