Product details
Overview
The MAX4018ESD+ from Analog Devices is a triple, high-speed, rail-to-rail output operational amplifier with enable/disable functionality, delivering 150MHz -3dB bandwidth, 600V/μs slew rate, and 400μA shutdown current. It operates from 3.3V to 10V single supply or ±1.65V to ±5V dual supplies, and is optimized for video line driving, analog-to-digital converter interface, and multiplexed signal routing in space-constrained systems.
For engineers reviewing the MAX4018ESD+ datasheet, MAX4018ESD+ pinout, MAX4018ESD+ application, or MAX4018ESD+ equivalent, key selection criteria include its 14-pin SO package, per-amplifier enable control (ENA/ENB/ENC), disabled output impedance of 35kΩ, and guaranteed performance across -40°C to +85°C.
Technical Context
The MAX4018ESD+ integrates three independent voltage-feedback op amps using current-feedback techniques to achieve wide bandwidth and fast settling (45ns to 0.1%). Each amplifier features rail-to-rail output swing (within 60mV of rails at 2kΩ), input common-mode range extending 200mV below VEE, and low distortion (-78dBc SFDR at 5MHz).
Its enable architecture supports independent channel shutdown via logic-level ENA/ENB/ENC pins, reducing quiescent current per amplifier to 400μA while placing outputs in high-impedance state (28–35kΩ, 2pF COUT(OFF)). This enables clean analog multiplexing without external switches or isolation resistors.

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 |
|---|---|---|---|
| MAX4018EEE+ | Same electrical specs but in 16-pin QSOP package - larger footprint, higher thermal resistance (8.3mW/°C derating) | Better suited for prototyping or manual soldering due to wider pin pitch; less optimal for dense video PCBs | Select MAX4018EEE+ only when SO-14 assembly capability is unavailable or thermal margin is critical |
| LMH6703MA/NOPB | Single-channel, 1.8GHz GBW, no enable function, higher supply current (12.5mA), requires external compensation | Used in ultra-wideband RF gain blocks or test equipment front-ends - not drop-in for multiplexed video routing | Choose LMH6703MA/NOPB only when bandwidth >150MHz is mandatory and per-channel shutdown is unnecessary |
Compared with MAX4018EEE+ and LMH6703MA/NOPB, the MAX4018ESD+ uniquely combines triple-channel integration, per-amplifier enable, SO-14 compactness, and broadcast-grade video linearity - making it the optimal choice for cost-sensitive, space-constrained video signal routing.

FAQ
What is the operating temperature range for the MAX4018ESD+?
The MAX4018ESD+ is specified for operation from -40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in surveillance enclosures, outdoor video equipment, and factory-floor instrumentation without thermal derating. All DC and AC parameters - including bandwidth, slew rate, and distortion - are guaranteed across this full range.
Does the MAX4018ESD+ require external compensation for unity-gain stability?
No, the MAX4018ESD+ is internally compensated for unity-gain stability. When configured as a unity-gain buffer, it requires only a 24Ω feedback resistor (RF) in series with the feedback path to optimize AC response and suppress peaking caused by parasitic LC resonance. No additional capacitors or network adjustments are needed.
How does the enable function behave during shutdown on the MAX4018ESD+?
When the enable pin (ENA, ENB, or ENC) is driven low, the corresponding amplifier enters shutdown mode: quiescent current drops to 400μA, and its output transitions to a high-impedance state (28–35kΩ) with only 2pF capacitance. Output voltage is undefined but presents negligible loading - ideal for analog multiplexing without signal contention.
Can the MAX4018ESD+ drive 75Ω video loads directly?
Yes, the MAX4018ESD+ delivers ±120mA output current and maintains rail-to-rail swing even into 75Ω loads. With proper termination (e.g., 75Ω to VCC/2 or ground), it achieves full 4.9VP-P output swing at 5V supply while preserving 0.02% differential gain accuracy - meeting SMPTE 259M and ITU-R BT.601 video standards.
What is the input common-mode voltage range of the MAX4018ESD+?
The MAX4018ESD+ input common-mode range extends from (VEE − 0.2V) to (VCC − 2.25V). In single-supply operation with VEE = 0V and VCC = 5V, this allows inputs from -0.2V to +2.75V - supporting ground-referenced signals and enabling level-shifting flexibility without clamping diodes or external bias networks.
