Product details
Overview
MAX4384EUP+ from Maxim Integrated is a quad-channel, rail-to-rail output, unity-gain-stable voltage-feedback op amp optimized for high-speed video and RF signal conditioning. It delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and 0.02%/0.08° differential gain/phase error, operating from +4.5V to +11V single supply or ±2.25V to ±5.5V dual supplies. It serves as a precision video line driver in broadcast-grade analog video routing systems.
For engineers reviewing the MAX4384EUP+ datasheet, MAX4384EUP+ pinout, MAX4384EUP+ application, or MAX4384EUP+ equivalent, this page provides verified electrical parameters, TSSOP-20 package mapping, disable-mode timing (1µs disable time), video-specific distortion metrics (-65dBc SFDR at 5MHz), and validated alternatives for multi-channel video amplifier replacement.
Technical Context
The MAX4384EUP+ integrates four independent amplifiers with individual shutdown control (DISABLEA–DISABLED), enabling selective channel power gating in video multiplexers. Each amplifier employs current-feedback techniques to achieve wide bandwidth while maintaining stability at unity gain.
Its input common-mode range extends beyond VEE (to VEE – 0.2V) and up to VCC – 2.25V, supporting ground-sensing operation in single-supply video systems. Output swing reaches within 50mV of both rails under 2kΩ load, delivering 4.9Vp-p dynamic range at +5V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4271DR | Single-channel, 1.3GHz bandwidth, higher power (12.5mA), no disable function. | Requires four separate packages for quad implementation; lacks per-channel shutdown. | Select when ultra-wide bandwidth (>500MHz) is required and discrete channel control is unnecessary. |
| LMH6738MQX | Quad-channel, 650MHz bandwidth, 12.5mA/channel, no rail-to-rail output. | Output swing limited to ~1.5V from rails; unsuitable for +5V video systems requiring full 0–5V swing. | Select for high-frequency RF applications where rail-to-rail output is not required and higher supply headroom exists. |

FAQ
What is the maximum capacitive load the MAX4384EUP+ can drive without instability?
The MAX4384EUP+ is not optimized for highly reactive loads. Driving >15pF directly causes peaking and potential oscillation. For capacitive loads above 10pF, an isolation resistor (10Ω–15Ω) must be placed in series with the output. Figure 5 in the datasheet shows stable closed-loop response with a 15Ω resistor and up to 120pF load. The MAX4384EUP+'s optimal isolation resistance vs. capacitive load curve (Figure 3) confirms this design requirement.
Does the MAX4384EUP+ support dual-supply operation, and what are the limits?
Yes, the MAX4384EUP+ operates from ±2.25V to ±5.5V dual supplies. At ±5V, the input common-mode range spans VEE to VCC – 2.25V (i.e., –5V to +2.75V), and output swing reaches within 0.4V of each rail under 150Ω load. The device maintains 210MHz bandwidth and –65dBc SFDR in dual-supply mode, making it suitable for legacy ±5V video infrastructure.
How does the disable function affect output impedance and settling behavior?
When DISABLEA–DISABLED are pulled low, each amplifier's output transitions to a high-impedance state with 35kΩ resistance and <2pF capacitance. Disable time is 1µs (from active to high-Z), and enable time is 100ns (from high-Z to active). This fast, high-isolation switching enables use in video multiplexers without signal contention or ghosting-critical for the MAX4384EUP+'s role in routing systems.
Can the MAX4384EUP+ drive a 75Ω video load while maintaining 0.1dB gain flatness?
Yes. The MAX4384EUP+ achieves 40MHz 0.1dB gain flatness into a 75Ω load (BW0.1dBLS), as specified in the AC Electrical Characteristics table. Its 75mA output drive capability and low 1.5Ω output impedance at 10MHz ensure minimal mismatch loss and reflection-meeting SMPTE and ITU-R BT.601 analog video transmission requirements.
What is the input common-mode voltage range for the MAX4384EUP+ in +5V single-supply operation?
In +5V single-supply operation (VEE = 0V, VCC = +5V), the input common-mode voltage range is –0.2V to +2.75V. This extends 200mV below ground (enabling true ground-sensing) and stops 2.25V below VCC-supporting DC-coupled video inputs with negative sync tips while maintaining >70dB CMRR across the range.
