Product details
Overview
The MAX4018EEE+ from Analog Devices is a triple, unity-gain-stable, rail-to-rail output operational amplifier with individual enable control per channel, delivering 150MHz -3dB bandwidth, 600V/μs slew rate, and 400μA shutdown supply 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 MAX4018EEE+ datasheet, MAX4018EEE+ pinout, MAX4018EEE+ application, or MAX4018EEE+ equivalent, key selection criteria include its 150MHz small-signal bandwidth, 0.02% differential gain error, 35kΩ disabled output impedance, 16-pin QSOP package, and per-channel ENA/ENB/ENC logic control for low-power multiplexing.
Technical Context
The MAX4018EEE+ implements a voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining unity-gain stability. Its input stage supports common-mode voltages extending 200mV below VEE and up to 2.25V below VCC, enabling ground-sensing operation in single-supply configurations.
Each of the three amplifiers features independent enable inputs (ENA, ENB, ENC) that reduce quiescent current to 400μA and raise output impedance to 35kΩ when asserted low, supporting active-high-impedance bus sharing without external isolation switches. Output drive capability remains ±120mA under enabled conditions with rail-to-rail swing within 60mV of either supply rail at 2kΩ load.
Key Specifications

|---|---|
| Small-Signal Bandwidth | 150MHz - Enables full NTSC/PAL video bandwidth and high-fidelity signal conditioning up to 75MHz fundamental. |
| Slew Rate | 600V/μs - Supports fast transient response for composite video pulses and high-speed data acquisition front-ends. |
| Supply Voltage Range | 3.3V to 10V single supply - Compatible with standard 3.3V, 5V, and industrial 9V rails without level-shifting. |
| Disabled Supply Current | 400μA per amplifier - Reduces system standby power by >92% versus active mode (5.5mA), critical for battery-powered instruments. |
| Differential Gain/Phase Error | 0.02%/0.02° - Meets broadcast-grade video fidelity requirements for set-top boxes and surveillance systems. |
| Output Drive Capability | ±120mA - Drives 75Ω coaxial lines, ADC input buffers, and multiple parallel loads without external buffering. |
| Disabled Output Impedance | 35kΩ - Provides effective channel isolation in video multiplexers, minimizing crosstalk and loading on active channels. |
Pinout & Package
The MAX4018EEE+ is housed in a 16-pin QSOP (Quarter Size Outline Package) with 0.154" body width and 0.025" lead pitch, RoHS-compliant and moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | INA+, INA−, OUTA | Amplifier A noninverting input, inverting input, and output - Fully independent signal path with dedicated enable (ENA, Pin 9). |
| 4, 5, 6 | INB+, INB−, OUTB | Amplifier B noninverting input, inverting input, and output - Matches A-channel performance; enabled via ENB (Pin 10). |
| 7, 8, 9 | INC+, INC−, OUTC | Amplifier C noninverting input, inverting input, and output - Third identical channel; enabled via ENC (Pin 11). |
| 10, 11 | ENB, ENC | Active-low enable inputs for Amplifiers B and C - Logic low disables output and reduces supply current to 400μA. |
| 12, 13 | VEE, VCC | Negative and positive supply pins - Support single-supply (VEE = GND) or dual-supply (VEE = −VS) operation. |
| 14, 15, 16 | N.C., N.C., ENA | No-connect pins and Amplifier A enable - ENA on Pin 16 allows independent control; N.C. pins must be left floating or grounded. |
Key Features
| Feature | Design Value |
|---|---|
| Per-channel enable logic | Three independent ENx inputs (Pins 9, 10, 11, 16) allow selective activation of any amplifier without affecting others - essential for dynamic channel routing. |
| Rail-to-rail output swing | Output swings within 60mV of VCC and VEE at 2kΩ load - maximizes dynamic range in 3.3V and 5V systems, improving SNR in ADC interfaces. |
| Low distortion at 5MHz | −78dBc SFDR and −75dB THD - preserves signal integrity in CCD imaging and high-resolution video digitization paths. |
| Input common-mode beyond VEE | Operates with inputs down to VEE − 0.2V - enables direct connection to ground-referenced sensors and single-ended sources without level shifters. |
| High-output impedance in shutdown | 35kΩ disabled output resistance with only 2pF capacitance - minimizes capacitive loading and crosstalk in multiplexer topologies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4016EUA+ | Dual-channel, 8-pin μMAX package; same 150MHz bandwidth and 400μA shutdown current but lacks third amplifier and QSOP footprint. | Suitable for dual-channel video or instrumentation where board area is constrained and third channel unnecessary. | Select MAX4016EUA+ when space is critical and only two amplifiers are required; not drop-in compatible due to pin count and package mismatch. |
| THS3201DR | Single-channel, 210MHz bandwidth, 3000V/μs slew rate; no shutdown feature; SO-8 package; higher supply current (12.5mA active). | Better suited for ultra-high-speed pulse amplification where power efficiency and multi-channel integration are secondary. | Choose THS3201DR only when bandwidth >200MHz is mandatory and per-channel disable is not needed; requires redesign for single-channel use. |
Compared with MAX4016EUA+, the MAX4018EEE+ adds a third channel and QSOP packaging for higher density; compared with THS3201DR, it trades raw speed for integrated enable control, lower power, and multi-channel economy-making it optimal for compact, power-aware video multiplexing.

FAQ
What is the operating supply voltage range for the MAX4018EEE+?
The MAX4018EEE+ operates from a single 3.3V to 10V supply or dual ±1.65V to ±5V supplies. This range supports common logic rails including 3.3V, 5V, and 9V industrial systems. The device maintains specified AC performance across this full range, with quiescent current scaling predictably from 5.5mA (enabled) to 400μA (disabled) per amplifier. Absolute maximum supply rating is 12V between VCC and VEE.
Does the MAX4018EEE+ support rail-to-rail input operation?
The MAX4018EEE+ supports rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends from VEE − 0.2V to VCC − 2.25V, enabling ground-sensing capability in single-supply configurations. While inputs can go slightly below VEE, they cannot reach VCC - limiting full rail-to-rail input operation. This design prioritizes high-speed performance and output drive over input range, making it ideal for buffered signal chains rather than direct sensor interfacing at VCC.
How does the enable function work on the MAX4018EEE+?
The MAX4018EEE+ provides three independent active-low enable inputs: ENA (Pin 16), ENB (Pin 9), and ENC (Pin 11). When pulled low, each corresponding amplifier shuts down, reducing its quiescent supply current to 400μA and placing its output in a high-impedance state (35kΩ). The enable threshold is defined by VIL ≤ VCC − 2.6V and VIH ≥ VCC − 1.6V, ensuring compatibility with standard CMOS logic levels. Amplifier response time is 100ns turn-on and 1μs turn-off.
What package type is used for the MAX4018EEE+?
The MAX4018EEE+ uses a 16-pin QSOP (Quarter Size Outline Package) with 0.154" body width and 0.025" lead pitch. It is RoHS-compliant (indicated by the "+" suffix) and rated moisture sensitivity level 3. This package offers higher pin density than SO-14 alternatives while maintaining surface-mount compatibility and thermal performance suitable for video signal-path layouts. Footprint dimensions and land patterns are documented in Maxim Integrated's official package drawings.
Can the MAX4018EEE+ drive 75Ω coaxial cables directly?
Yes, the MAX4018EEE+ can drive 75Ω coaxial cables directly when configured in unity-gain with proper termination. Its ±120mA output drive capability and 600V/μs slew rate support full-amplitude NTSC video signals. For optimal performance, use the recommended 24Ω series feedback resistor (RF) and match source and load impedances. Layout best practices include microstrip routing, local 0.1μF VCC bypassing, and avoiding stubs or vias near the output node to preserve signal integrity up to 150MHz.
