Product details
Overview
MAX4380EXT-T from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output operational amplifier with integrated disable function, designed for high-speed video and analog signal conditioning. It delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and 55MHz 0.1dB gain flatness while operating from +4.5V to +11V single supply. Its 6-pin SC70 package and 5.5mA quiescent current make it ideal for space-constrained, low-power video line drivers and ADC interface circuits.
For engineers reviewing the MAX4380EXT-T datasheet, MAX4380EXT-T pinout, MAX4380EXT-T application, or MAX4380EXT-T equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The MAX4380EXT-T 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 200mV below VEE (ground in single-supply use) and up to 2.25V below VCC, enabling ground-sensing operation in +5V systems.
It integrates a logic-controlled disable feature that places the output in high-impedance state (27–35kΩ) with <1µs disable time, making it suitable for multiplexed video routing. The device is internally compensated for stable unity-gain operation and optimized for driving 75Ω video loads with 0.02% differential gain error and 0.08° differential phase error.

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 no disable function; 12.5mA IQ; SO-8 package (larger footprint). | Lacks integrated disable, requiring external MOSFET switching for power gating in mux systems. | Choose when absolute bandwidth >1GHz is required and board area permits SO-8; avoid where disable functionality is mandatory. |
| ADA4817-1ACPZ-R7 | 1GHz GBW, 250V/µs slew rate, 1.3mA IQ, 0.9nV/√Hz noise; LFCSP-8 package. | Lower noise and power, but no dedicated disable pin-requires GPIO-controlled enable circuitry. | Prefer for ultra-low-noise precision instrumentation; not drop-in for video line driver disable use cases. |
Compared with LMH6702MF/NOPB and ADA4817-1ACPZ-R7, the MAX4380EXT-T uniquely combines 210MHz bandwidth, rail-to-rail output, and integrated disable in a 6-pin SC70-enabling compact, low-power, and multiplexed video signal routing without external switching components.

FAQ
What is the operating supply voltage range for the MAX4380EXT-T?
The MAX4380EXT-T operates from a single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. At +5V single supply, it delivers rail-to-rail output swing within 50mV of each rail into 2kΩ, supporting low-voltage video and portable instrumentation designs. Absolute maximum supply voltage is +12V.
Does the MAX4380EXT-T support rail-to-rail input operation?
The MAX4380EXT-T does not support full rail-to-rail input: its input common-mode range extends from (VEE − 0.2V) to (VCC − 2.25V). In +5V operation (VEE = 0), this means inputs can go from −0.2V to +2.75V - enabling ground-sensing capability but not positive rail access. This design prioritizes video DC accuracy over full input range.
How does the DISABLE pin function on the MAX4380EXT-T?
The DISABLE pin on the MAX4380EXT-T is active-low: pulling it to VEE (ground) places the output in high-impedance state (27–35kΩ), with typical disable time of 1µs. Pulling it to VCC enables normal operation. This allows seamless integration into video multiplexers and power-gated signal paths without external switches.
Can the MAX4380EXT-T drive a 75Ω video load directly?
Yes - the MAX4380EXT-T is characterized to drive 75Ω loads with specified differential gain/phase (0.02%/0.08°), output current (≥50mA sourcing/sinking), and 0.1dB gain flatness to 55MHz. Its output stage is optimized for video line driving, eliminating need for external emitter followers in most standard-definition and HD applications.
What is the typical quiescent current of the MAX4380EXT-T?
The MAX4380EXT-T draws 5.5mA quiescent supply current per amplifier under normal operation (DISABLE = VCC). When disabled (DISABLE = VEE), quiescent current drops to 0.45–0.6mA - a >90% reduction - making it highly suitable for battery-powered instruments and systems requiring periodic signal path shutdown.
