Product details
Overview
The MAX4018ESD from Analog Devices is a triple, unity-gain-stable, rail-to-rail output operational amplifier with enable/disable control, 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 5.5mA quiescent current (enabled), high-output impedance in disable mode (35kΩ), and confirmed performance in NTSC video (0.02% differential gain error).
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%). Its input common-mode range extends 200mV below VEE and to within 2.25V of VCC, enabling ground-sensing operation in single-supply configurations.
Each amplifier features an active enable input (EN) that places the output in high-impedance state (28–35kΩ) with only 400–650μA total supply current for the entire device. The 14-pin SO package supports compact layout while maintaining isolation between channels (crosstalk ≤ –95dB at 10MHz).

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+T | Same electrical specs; 16-pin QSOP package with 0.65mm pitch and smaller footprint (5.0mm × 4.4mm) | Better suited for ultra-dense PCB layouts; requires different land pattern and reflow profile | Select MAX4018EEE+T when board area is constrained and assembly supports fine-pitch SOIC alternatives |
| LMH6703MA/NOPB | Single-channel, 1.3GHz GBW, no enable feature; 8-pin SOIC; higher supply current (12.5mA) | Lacks per-channel disable and triple integration; used where extreme bandwidth outweighs power/integration needs | Choose LMH6703MA/NOPB only for single-ended, non-multiplexed >500MHz signal paths where MAX4018ESD's 150MHz is insufficient |
Compared with MAX4018EEE+T, the MAX4018ESD offers identical performance in a more manufacturable 14-pin SO package, while the LMH6703MA/NOPB trades integration and power efficiency for raw bandwidth-making it unsuitable for multiplexed or battery-powered use cases.

FAQ
What is the operating temperature range for the MAX4018ESD?
The MAX4018ESD is specified for continuous operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in surveillance systems, portable test equipment, and factory automation environments where thermal stability is critical. All AC and DC parameters-including bandwidth, slew rate, and distortion-are guaranteed across this full range.
Does the MAX4018ESD support single-supply operation?
Yes, the MAX4018ESD fully supports single-supply operation from 3.3V to 10V. Its input common-mode range extends 200mV below VEE (ground), and its rail-to-rail output swings within 60mV of both supply rails under 2kΩ load. This enables direct interfacing with ground-referenced sensors and low-voltage ADCs without level-shifting circuitry.
How does the enable/disable function work on the MAX4018ESD?
The MAX4018ESD provides three independent enable inputs (ENA, ENB, ENC), each controlling one amplifier. Driving any EN pin low disables its corresponding amplifier, reducing that channel's supply current to near-zero and placing its output in a high-impedance state (35kΩ typical). Total device shutdown current is 400–650μA, enabling dynamic power scaling in multi-channel systems.
What is the small-signal bandwidth of the MAX4018ESD?
The MAX4018ESD has a small-signal –3dB bandwidth of 150MHz when configured for unity gain (AVCL = 1) with a 20mVP–P output signal. This specification applies to all three amplifiers and is measured under standard conditions (VCC = 5V, VEE = 0V, RL = 100Ω to VCC/2, TA = +25°C). Bandwidth remains ≥140MHz for 2VP–P large-signal conditions.
Can the MAX4018ESD drive 75Ω video loads directly?
Yes, the MAX4018ESD can drive 75Ω video loads directly. It delivers ±120mA output current and maintains 0.02% differential gain error into 150Ω (standard video termination), confirming robust performance into 75Ω with appropriate gain-setting resistors. For optimal NTSC/PAL fidelity, use RF = 24Ω in unity-gain configuration and ensure proper PCB layout with controlled impedance traces.
