Product details
Overview
MAX4382ESD+ from Maxim Integrated is a quad-channel, rail-to-rail output, high-speed voltage-feedback operational amplifier with disable functionality, delivering 210MHz -3dB bandwidth, 485V/µs slew rate, and 55MHz 0.1dB gain flatness on a +4.5V to +11V single supply - optimized for video line driving, CCD imaging, and analog-to-digital converter interface applications.
For engineers reviewing the MAX4382ESD+ datasheet, MAX4382ESD+ pinout, MAX4382ESD+ application, or MAX4382ESD+ equivalent, this page provides verified circuit role (quad video buffer with shutdown), package mapping (14-pin SO), key AC/DC specs, real-world application context, and validated alternative options for video signal conditioning designs.
Technical Context
The MAX4382ESD+ implements a current-feedback-enhanced voltage-feedback architecture to achieve wide bandwidth and fast settling (16ns to 0.1%). It supports rail-to-rail output swing within 50mV of each supply rail under 2kΩ load and accepts input common-mode voltages extending 200mV below VEE and up to 2.25V below VCC.
Each of its four amplifiers features independent disable control (DISABLEA–DISABLED), placing outputs in high-impedance state (27–35kΩ) with <2pF capacitance - enabling use in RF/video multiplexing and switching systems without external isolation switches.

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 |
|---|---|---|---|
| MAX4382EUD+ | Same electrical specs but in 14-pin TSSOP (4.4mm width) instead of SO (8.6mm); thinner profile, finer pitch | Better suited for space-constrained PCBs where SO footprint is prohibitive; thermal resistance differs (727mW vs 667mW derating) | Select MAX4382EUD+ when board area is limited and reflow compatibility with fine-pitch components is confirmed |
| LMH6738MA/NOPB | Quad 650MHz GBW op amp; higher bandwidth but no disable function; 12.6mA per amp quiescent current | Used in RF signal chains requiring >300MHz small-signal BW; lacks channel shutdown, limiting multiplexer use | Choose LMH6738MA/NOPB only when bandwidth >300MHz is mandatory and disable functionality is unnecessary |
Compared with MAX4382EUD+, MAX4382ESD+ offers superior thermal dissipation margin in SO packaging and easier hand-soldering; versus LMH6738MA/NOPB, it trades bandwidth for lower power, integrated disable, and video-optimized distortion performance.

FAQ
What is the operating supply voltage range for the MAX4382ESD+?
The MAX4382ESD+ operates from a single +4.5V to +11V supply or dual ±2.25V to ±5.5V supplies. At +5V single supply, it delivers full 210MHz bandwidth and rail-to-rail output swing. The device's PSRR remains ≥50dB across this range, ensuring robust noise rejection in noisy industrial environments where MAX4382ESD+ is commonly deployed.
Does the MAX4382ESD+ support rail-to-rail input operation?
The MAX4382ESD+ supports rail-to-rail *output*, but its input common-mode range extends from VEE − 0.2V to VCC − 2.25V - meaning it senses down to 200mV below ground in single-supply mode, yet does not reach VCC at the input. This ground-sensing capability makes MAX4382ESD+ ideal for interfacing with legacy video sources and sensors referenced to system ground.
How does the disable function work on the MAX4382ESD+?
Each amplifier in the MAX4382ESD+ has a dedicated active-low DISABLEx pin (pins 4, 10, 14, and - for quad version - pin 12 is DISABLEC; note MAX4382ESD+ uses DISABLEA/B/C only as it is quad, not quad+). Pulling DISABLEx low places that amplifier's output in high-impedance state (27–35kΩ), drawing only 0.45–0.6mA quiescent current. This feature is integral to MAX4382ESD+'s use in video multiplexers and power-aware systems.
What is the small-signal -3dB bandwidth of the MAX4382ESD+?
The MAX4382ESD+ delivers a guaranteed 210MHz small-signal -3dB bandwidth (VOUT = 100mVp-p) at +5V supply, TA = +25°C. This specification is maintained across the full −40°C to +85°C temperature range and enables reliable use in high-definition video distribution, digital camera processing, and broadband test equipment where MAX4382ESD+ serves as a critical signal path element.
Can the MAX4382ESD+ drive a 75Ω video load directly?
Yes - the MAX4382ESD+ is characterized to drive 75Ω loads with 0.02% differential gain and 0.08° phase error (NTSC), supporting video line driver applications without external buffers. Its output delivers ±50mA into 75Ω and sustains 485V/µs slew rate even under this load, making MAX4382ESD+ suitable for direct coaxial cable driving in surveillance and broadcast infrastructure.
